General Description

The MAX8532 offers the benefits of low-dropout voltage

and ultra-low power regulation in a subminiaturized

UCSP, making it ideal for space-restricted portable

equipment. The device operates from a 2.5V to 6.5V

input and delivers up to 200mA, with low dropout of

100mV (typ) at 100mA. Designed with an internal

P-channel MOSFET pass transistor, the supply current

is kept at a low 80µA, independent of the load current

and dropout voltage. Other features include short-circuit

protection and thermal-shutdown protection.

The MAX8532 includes a reference bypass pin for low

input. The device is available in a tiny 6-pin UCSP.
