AAT3258
300mA LDO Linear Regulator with μP Reset

General Description
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.
