SC1457

150mA Ultra Low Dropout

Regulator with Undervoltage Flag

POWER MANAGEMENT

Description

Features

The SC1457 is a low dropout linear regulator that

operates from a +2.25V to +6.5V input range and

delivers up to 150mA. A PMOS pass transistor allows

the low 75µA supply current to remain independent of

load, making these devices ideal for battery operated

portable equipment such as cellular phones, cordless

phones and personal digital assistants.

Guaranteed 150mA output current

Error flag indicates output undervoltage fault

2% output accuracy guaranteed over line, load and

temperature

Very small external components - designed to work

with ceramic capacitors

Low 110µV_RMSoutput noise

Very low supply current

Thermal overload protection

Reverse battery protection

Low power shutdown

Full industrial temperature range

Very low profile packaging available (1mm max.

height)

Surface mount packaging (SOT-23-5 and

TSOT-23-5)

The SC1457 has very low dropout voltage (typically 1.1mV

at light loads and 150mV at 150mA) with better than

1.5% initial output voltage accuracy. It has a logic

compatible enable control input and an internal output

undervoltage monitor.

Designed especially for hand held, battery powered

devices, the SC1457 can be switched by a CMOS or TTL

compatible logic signal. When disabled, power

consumption drops nearly to zero. Other features include

short circuit protection, thermal shutdown protection and

reverse battery protection.

Applications

Battery Powered Systems

Cellular Telephones

Cordless Telephones

Personal Digital Assistants

Portable Instrumentation

Modems

The SC1457 is available in several fixed voltages in the

tiny 5 lead SOT-23 package and the ultra low profile 5

lead TSOT-23.
