SC4211

Very Low Input /Very Low Dropout

1 Amp Regulator With Enable

POWER MANAGEMENT

Description

Features

The SC4211 is a high performance positive voltage

regulator designed for use in applications requiring very

low Input voltage and very low dropout voltage at up to 1

amp. It operates with a Vin as low as 1.4V, with output

voltage programmable as low as 0.5V. The SC4211 fea-

tures ultra low dropout, ideal for applications where Vout

is very close to Vin. Additionally, the SC4211 has an en-

able pin to further reduce power dissipation while shut-

down. The SC4211 provides excellent regulation over varia-

tions in line, load and temperature.

Input Voltage as low as 1.4V

250mV dropout @ 1A

Adjustable output from 0.5V to 3.3V

Over current and over temperature protection

Enable pin

10µA quiescent current in shutdown

Low reverse leakage (output to input)

Full industrial temperature range

Available in SOIC-8EDP package

The SC4211 is available in the SOIC-8EDP (Exposed Die

Pad) package. The output voltage can be set via an exter-

nal divider or to 0.5V depending on how the FB pin is con-

figured.
