AMS3120

2A Fast Transient Linear Regulator

General Description

Features

The AMS3120 is a high performance linear regulator

with very low dropout voltage and excellent transient

response. It is designed to operate with wide input

voltage range of 1.5 – 7Volts making it ideal for two

step conversion while maintaining high efficiency for

many power sensitive applications. The device is

capable of supplying 2A of output current with a

typical dropout voltage of 550mV at 2A. The product

is available in either fixed or adjustable output

voltage.

•

V_INrange: 1.5 – 7V

Fixed and Adjustable output voltage as low

as 0.6V

•

2A maximum output current

550mV typical dropout voltage at 2A

Low self noise

Optional Power Good (PG) output

Enable (EN) pin for LDO on/off

125µA typical supply current

PSRR >40dB at 10KHz

The linear regulator has been optimized for noise

sensitive applications.

The device includes an

Stable with Electrolytic, Tantalum or

Ceramic capacitors

Enable pin for electrical on/off of the regulator.

Forcing the Enable pin to logic low shuts down the

LDO and reduces the supply current to less than

1µA.

•

Current Limit protection

Over-Temperature Shutdown

-40 to +125°C temperature range

The product includes complete short-circuit and

thermal protection. The combination of these two

internal protection circuits gives the device a

comprehensive safety system to safe guard against

extreme adverse operating conditions.

Thermally enhanced SOIC-8 exposed

paddle package

RoHS & WEEE compliant

•

Applications

The AMS3120 is available in a thermally enhanced

SOIC-8 EDP package, and it is rated for -40°C to

+125°C temperature range.
