ADP1764 Description

The ADP1764 is a low noise, low dropout (LDO) linear regulator. It is designed to operate from a single input supply with an input voltage as low as 1.10 V without the requirement of an external bias supply to increase efficiency and provide up to 4 A of output current (I_OUT).

The low 47 mV typical dropout voltage at a 4 A load allows the ADP1764 to operate with a small headroom while maintaining regulation and providing better efficiency.

The ADP1764 is optimized for stable operation with small 22 μF ceramic output capacitors. The ADP1764 delivers optimal transient performance with minimal printed circuit board (PCB) area.

The ADP1764 is available in fixed output voltages ranging from 0.55 V to 1.5 V. The output voltage (V_OUT) of the adjustable output model can be set from 0.5 V to 1.5 V through an external resistor connected between VADJ and ground.

The ADP1764 has an externally programmable soft start time by connecting a capacitor to the SS pin. Short-circuit and thermal overload protection circuits prevent damage in adverse conditions. The ADP1764 is available in a small, 16-lead LFCSP package for the smallest footprint solution to meet a variety of applications.
