150mA ULTRA LOW DROPOUT

MICROPOWER LINEAR REGULATOR

SC112

PRELIMINARY - November 17, 1999

TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com

DESCRIPTION

FEATURES

The SC112 is a 150mA ultra low dropout linear

regulator with a built in CMOS/TTL logic level enable,

designed specifically for battery powered applications

where low quiescent current and low dropout are

critical for battery longevity.

•

Low dropout voltage

CMOS/TTL compatible control switch

Very low quiescent current 60µA (ON, no load)

Internal thermal shutdown

Short circuit protection

Very low standby current 0.1µA maximum (OFF)

Low noise with external bypass capacitor

Industrial temperature range

The SC112 uses a Semtech proprietary internal PNP

device for the pass element, providing a low dropout

voltage of 130mV at a load of 60mA.

The output noise is reduced to 30µV (typical) by

placing a very low leakage 10nF capacitor on pin 3

(noise bypass).

APPLICATIONS

•

Battery powered systems

Cellular telephones

Cordless telephones

Pagers, personal digital assistants

Portable instrumentation

Low voltage systems

Each device contains a bandgap reference, error

amplifier, PNP pass element, thermal and current

limiting circuitry and resistor divider network for setting

output voltage.

The SC112 is packaged in a six lead SOT-23 surface

mount package for a very small footprint and it requires

only a 1µF capacitor on the output and a 0.01µF on the

bypass pin for a minimum number of external

components.
