LP3997

Micropower 250mA CMOS LDO Regulator with Error

Flag / Power-On-Reset

General Description

The LP3997 regulator is designed to meet the requirements

of portable, battery-powered systems, providing accurate

output voltage, low noise, and low quiescent current. The

LP3997 provides 3.3V output at up to 250mA load current.

When switched in shutdown mode, the power consumption

is virtually zero.

The LP3997 is designed to be stable with space saving

ceramic capacitors as small as 1µF.

The LP3997 also includes an out-of-regulation error flag.

When the output is more than 5% below its nominal voltage,

the error flag sets to low. If a capacitor is connected to

device’s delay pin, a delayed power-on reset signal will be

generated.
