The ADM7160 is an ultralow noise, low dropout linear regulator that operates from 2.2 V to 5.5 V and provides up to 200 mA of output current. The low 150 mV dropout voltage at 200 mA load improves efficiency and allows operation over a wide input voltage range.Using an innovative circuit topology, the ADM7160 achieves ultralow noise performance without the need for a bypass capacitor, making it ideal for noise-sensitive analog front end and RF applications. The ADM7160 also achieves ultralow noise performance without compromising PSRR or transient line and load performance.Current-limit and thermal overload protection circuits prevent damage under adverse conditions. The ADM7160 also includes an internal pull-down resistor on the EN input.The ADM7160 is specifically designed for stable operation with tiny 1 μF, ±30% ceramic input and output capacitors to meet the requirements of high performance, space constrained applications.The ADM7160 is available in tiny 5-lead TSOT and 6-lead LFCSP packages with 16 fixed output voltage options, ranging from 1.1 V to 3.3 V. The LFCSP offers a very compact solution that provides excellent thermal performance for applications that require up to 200 mA of output current in a small, low profile footprint.Applications ADC/DAC power supplies RF, VCO, and PLL power supplies Post dc-to-dc regulation

The ADM8323/ADM8324 are supervisory circuits that monitor power supply voltage levels and code execution integrity in microprocessor-based systems. An on-chip watchdog timer checks for activity within a preset timeout window. A reset signal can also be asserted by an external push-button switch through a manual reset input. The RESET output is either push-pull (ADM8323) or open-drain (ADM8324).A watchdog failure results in a low output on the RESET pin. A failure can be triggered either by a fast watchdog error (watchdog pulses too close together) or by a slow watchdog error (no watchdog pulse within the timeout period). This effectively gives a window to observe the watchdog pulse. The watchdog timeout is measured from the last falling edge of the watchdog input (WDI). There are eight different watchdog windows available, as shown in Table 5.Each device is available in a choice of 26 reset threshold options from 2.5 V to 5 V in 100 mV increments. There are also four reset timeout options of 1 ms, 20 ms, 140 ms, and 1120 ms (minimum). Not all device options are available as standard models. See the Ordering Guide for details.The ADM8323/ADM8324 are available in a 5-lead SOT-23 package and typically consume only 10 μA, making them suitable for use in low power portable applications.Applications Automotive Microprocessor systems Computers Controllers Intelligent instruments Portable equipment
