AAT3258

300mA LDO Linear Regulator with µP Reset

™

PowerLinear

General Description

Features

The AAT3258 combines a high performance, low

noise, 300mA low dropout (LDO) linear regulator

with a microprocessor reset monitor. The 300mA

output capability of the LDO regulator makes this

device ideal for use with microprocessors and DSP

cores in portable products. The microprocessor

reset monitor section has very low quiescent cur-

rent consumption and has an active low reset out-

put. The AAT3258 has separate input pins for the

reset monitor and LDO regulator so they may be

operated from independent sources for increased

design flexibility. This device features very low qui-

escent current, typically less than 71µA.

The LDO regulator has low dropout voltage, typical-

ly 400mV at the full output current level, making it

ideal for portable applications where extended bat-

tery life is critical. The AAT3258 LDO regulator sec-

tion has complete over-current/short-circuit and

over-temperature protection circuits to guard against

extreme operating conditions. The device also has

an active output pull down function when disabled.

•

The AAT3258 is available in a space-saving 8-pin

TSOPJW package. This device is capable of oper-

ation over a -40°C to +85°C temperature range.
