SC1454

Dual 150mA Ultra Low

Dropout, Low Noise Regulator

POWER MANAGEMENT

Description

Features

The SC1454 contains two ultra low dropout voltage

regulators (ULDOs). It operates from an input voltage

range of 2.25V to 6.5V, and a wide variety of output

voltage options are available. One ULDO has a fixed

output, and the other is either fixed (SETA pin grounded)

or adjustable using external resistors. Each ULDO has an

independent enable pin.

Up to 150mA per regulator output

Low quiescent current

Low dropout voltage

Stable operation with ceramic caps

Very low 50µV_RMSoutput noise

Wide selection of output voltages

Tight load and line regulation

Current and thermal limiting

Reverse input polarity protection

<1.5uA off-mode current

The SC1454 has a bypass pin to enable the user to

capacitively decouple the bandgap reference for very low

output noise (50µV_RMStypically).

Logic controlled enable

Designed specifically for battery operated systems, the

devices utilize CMOS technology to require very low

operating currents (typically 130µA with both outputs

supplying 150mA). In addition, the dropout voltage is

typically 155mV at 150mA, helping to prolong battery

life further. The devices are designed to provide 400mA

of peak current for applications which require high initial

inrush current.

Applications

Cellular telephones

Palmtop/Laptop computers

Battery-powered equipment

Bar code scanners

SMPS post regulator/dc to dc modules

High efficiency linear power supplies

They have been designed to be used with low ESR

ceramic capacitors to save cost and PCB area.

The SC1454 is available with a wide variety of voltage

options as standard. It comes in the tiny 8 lead MSOP

surface mount package.
