MAX8532EBT

Manufacturer Part Number
MAX8532EBT
Description
Low-Noise, Low-Dropout,200mA Linear Regulator in UCSP
Manufacturer
MAXIM [Maxim Integrated Products]
Datasheet
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
output noise (40µV
input. The device is available in a tiny 6-pin UCSP.
