LP3997

Micropower 250mA CMOS LDO Regulator with Error

Flag / Power-On-Reset

n Less than 70µA Typical I_Qat 250mA.

n Virtually Zero I_Q(Disabled).

The LP3997 regulator is designed to meet the requirements

n Themal and Short Circuit Protection.

General Description

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.

n 3.3V Output.

n For other voltage options, please contact your local NSC

sales office.

The LP3997 is designed to be stable with space saving

ceramic capacitors as small as 1µF.

Package

8 Lead MSOP

For other package options contact your NSC sales office.

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.

Applications

n Portable Consumer Electronics

n Cellular Handsets

n Laptop and Palm Computers

n PDA’s

Features

n Low, 140mV, Dropout at 250mA Load.

n Stable with Ceramic Capactor.

n Low Noise, with Bypass Capacitor.

n Digital Cameras
