The LTC4227 offers ideal diode-OR and Hot Swap™ functions for two power rails by controlling external Nchannel MOSFETs. MOSFETs acting as ideal diodes replace two high power Schottky diodes and the associated heat sinks, saving power and board area. A Hot Swap control MOSFET allows a board to be safely inserted and removed from a live backplane by limiting inrush current. The supply output is also protected against short-circuit faults with a fast acting current limit and internal timed circuit breaker.The LTC4227 regulates the forward voltage drop across the MOSFETs to ensure smooth current transfer from one supply to the other without oscillation. The ideal diodes turn on quickly to reduce the load voltage droop during supply switchover. If the input supply fails or is shorted, a fast turn-off minimizes reverse-current transients.The LTC4227 allows turn-on/off control, and reports fault and power good status for the supply.

The AD688 is a high precision ±10 V tracking reference. Low tracking error, low initial error and low temperature drift give the AD688 reference absolute ±10 V accuracy performance previously unavailable in monolithic form. The AD688 uses a proprietary ion-implanted buried Zener diode, and laser-wafer-drift- trimming of high stability thin-film resistors to provide outstanding performance at low cost.The AD688 includes the basic reference cell and three additional amplifiers. The amplifiers are laser-trimmed for low offset and low drift and maintain the accuracy of the reference. The amplifiers are configured to allow Kelvin connections to the load and/or boosters for driving long lines or high current loads, delivering the full accuracy of the AD688 where it is required in the application circuit.The low initial error allows the AD688 to be used as a system reference in precision measurement applications requiring 12-bit absolute accuracy. In such systems, the AD688 can provide a known voltage for system calibration and the cost of periodic recalibration can therefore be eliminated. Furthermore, the mechanical instability of a trimming potentiometer and the potential for improper calibration can be eliminated by using the AD688 and calibration software.The AD688 is available in three versions. The AD688AQ and BQ grades are packaged in 16-pin cerdip (0.3') packages and are specified for operation from -40°C to +85°C. The AD688SQ grade is specified for operation from -55°C to +125°C.PRODUCT HIGHLIGHTS Precision Tracking. The AD688 offers precision tracking ±10 V Kelvin output connections with no external components. Tracking error is less than 1.5 mV and fine-trim is available for applications requiring exact symmetry between the +10 V and −10 V outputs.  Accuracy. The AD688 offers 12-bit absolute accuracy without any user adjustments. Optional fine-trim connections are provided for applications requiring higher precision. The fine-trimming does not alter the operating conditions of the Zener or the buffer amplifiers and thus does not increase the temperature drift.  Low output noise. Output noise of the AD688 is low— typically 6 μVp-p. A pin is provided for broadband noise filtering using an external capacitor.

The ADP3303 is a member of the ADP3300, ADP3301, andADP3309 family of precision low dropout anyCAP voltage regulators. The ADP3303 stands out from the conventional LDOs with a different architecture, an enhanced process, and adifferent package. Its patented design requires only a 0.47 μFoutput capacitor for stability. This device is insensitive to capacitor Equivalent Series Resistance (ESR) and is stable with any good quality capacitor, including ceramic types (MLCC) forspace restricted applications. The ADP3303 achievesexceptional accuracy of ±0.8% at room temperature and ±1.4%overall accuracy over temperature, line, and load regulations.The dropout voltage of the ADP3303 is only 180 mV (typical) at 200 mA.In addition to the architecture and process, the Analog Devices, Inc., proprietary thermally enhanced package (Thermal Coastline)can handle 1 W of power dissipation without external heatsink or large copper surface on the printed circuit board (PCB).This keeps PCB real estate to a minimum and makes theADP3303 very attractive for use in portable equipment.The ADP3303 operates with a wide input voltage range from 3.2 V to 12 V and delivers a load current in excess of 200 mA.It features an error flag that signals when the device is about to lose regulation or when the short circuit or thermal overloadprotection is activated. Other features include shutdown and optional noise reduction capabilities. The ADP3300, ADP3301,and ADP3309 anyCAP LDO family offers a wide range of output voltages and output current levels:ADP3300 (50 mA, SOT-23)ADP3301 (100 mA) ADP3302 (100 mA, Dual Output)Applications Cellular telephones Notebook, palmtop computers Battery powered systems Portable instruments Post regulator for switching supplies Bar code scanners

The LT3468/LT3468-1/LT3468-2 are highly integrated ICs designed to charge photoflash capacitors in digital and film cameras. A patented control technique* allows for the use of extremely small transformers. Each device contains an on-chip high voltage NPN power switch. Output voltage detection* is completely contained within the device, eliminating the need for any discrete zener diodes or resistors. The output voltage can be adjusted by simply changing the turns ratio of the transformer. The LT3468 has a primary current limit of 1.4A, the LT3468-2 has a 1A limit, and the LT3468-1 has a 0.7A limit. These different current limit levels result in well controlled input currents of 500mA for the LT3468, 375mA for the LT3468-2 and 225mA for the LT3468-1. Aside from the differing current limit, the three devices are otherwise equivalent.The CHARGE pin gives full control of the part to the user. Driving CHARGE low puts the part in shutdown. The DONE pin indicates when the part has completed charging. The LT3468 series of parts are available in tiny low profile (1mm) SOT-23 packages.Applications Digital / Film Camera Flash PDA / Cell Phone Flash Emergency Strobe

The LT1031/LT0070 are precision 10V references with ultralow drift and noise, extremely good long term stability, and almost total immunity to input voltage variations. The reference output will both source and sink up to 10mA and can be used as a shunt regulator (two terminal Zener) with the same precision characteristics as the three terminal connection. Special care has been taken to minimize thermal regulation effects and temperature induced hysteresis.The LT1031 reference is based on a buried Zener diode structure which eliminates noise and stability problems associated with surface breakdown devices. Further, a subsurface Zener exhibits better temperature drift and time stability than even the best band-gap references.Unique circuit design makes the LT1031 the first three terminal IC reference to offer ultralow drift without the use of high power on-chip heaters. Output voltage is pretrimmed to 0.05% accuracy.The LT1031 can be used as a plug-in replacement for the AD581 and LH0070*, with improved electrical and thermal performance.Applications A-to-D and D-to-A Converters Precision Regulators Digital Voltmeters lnertial Navigation Systems Precision Scales Portable Reference Standard
