The ADP1752 / ADP1753 are CMOS, low dropout linear regulators that operate from 1.6 V to 3.6 V and provide up to 800mA of output current. These low VIN & VOUT LDOs are ideal for regulation of nanometer FPGA geometries operating from 2.5V down to 1.8V I/O rails, and powering core voltages down to 0.75V. Using an advanced proprietary architecture, they provide high power supply rejection, low noise, and achieve excellent line and load transient response with a small 4.7 µF ceramic output capacitor.The ADP1752 is available in 7 fixed output voltage options. The ADP1753 is available in an adjustable version, which allows output voltages that range from 0.75 V to 3.0 V via an external divider. The ADP1752 / ADP1753 allows an external soft start capacitor to be connected to program the start-up. A power good output allows power system monitors to digitally check the health of the output power rail voltage.The ADP1752 / ADP1753 are available in a 16-lead, 4 mm × 4 mm LFCSP, making them not only very compact solutions, but also providing excellent thermal performance for applications requiring up to 800mA of output current in a small, low profile footprint.APPLICATIONS Server computers Memory components Telecommunications equipment Network equipment DSP/FPGA/microprocessor supplies Instrumentation equipment/data acquisition systems

The LTC3604 is a high efficiency, monolithic synchronous buck regulator using a phase-lockable controlled on-time, current mode architecture capable of supplying up to 2.5A of output current. The operating supply voltage range is from 3.6V to 15V, making it suitable for a wide range of power supply applications. The operating frequency is programmable from 800kHz to 4MHz with an external resistor enabling the use of small surface mount inductors. For switching noise sensitive applications, the LTC3604 can be externally synchronized over the same frequency range. An internal phase-locked loop aligns the on-time of the top power MOSFET to the internal or external clock. This unique constant frequency/controlled on-time architecture is ideal for high step-down ratio applications that demand high switching frequencies and fast transient response. The LTC3604 offers two operational modes: Burst Mode operation and forced continuous mode to allow the user to optimize output voltage ripple, noise, and light load efficiency for a given application. Maximum light load efficiency is achieved with the selection of Burst Mode operation while forced continuous mode provides minimum output ripple and constant frequency operation.Applications Distributed Power Systems Lithium-Ion Battery-Powered Instruments Point-of-Load Power Supplies
