DUAL 150mA LDO REGULATOR WITH

PROGRAMMABLE RESET

SC1452

PRELIMINARY - August 7, 2000

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

DESCRIPTION

FEATURES

•= ^{Up to 150mA per regulator output}

The SC1452 is a state of the art device intended to

provide maximum performance and flexibility in battery

operated systems. It has been designed specifically to

fully support a single Li-Ion battery and its external

charger voltages.

•= Low quiescent current

•= Low dropout voltage

•= Wide selection of output voltages

•= Stable operation with ceramic caps

•= Tight load and line regulation

•= Current and thermal limiting

•= Reverse input polarity protection

•= <1uA off-mode current

The SC1452 contains two independently enabled, ultra

low dropout voltage regulators (ULDOs). It operates

from an input voltage range of 2.5V to 6.5V, and a wide

variety of output voltage options are available which are

designed to provide an initial tolerance of ±1% and

±2% over temperature.

•= Logic controlled electronic enable

•= Programmable reset

•= Full industrial temperature range

Each regulator has an associated active-low reset sig-

nal which is asserted when the voltage output declines

below the preset threshold. Once the output recovers,

the reset continues to be asserted (delayed) for a

predetermined time, 50ms for reset A and 150ms for

reset B. In the case of regulator B, the delay time may

be reduced by the addition of an external capacitor.

APPLICATIONS

•= Cellular telephones

•= Palmtop/Laptop computers

•= Battery-powered equipment

•= Bar code scanners

•= SMPS post regulator/dc to dc modules

•= High efficiency linear power supplies

The SC1452 has a bypass pin to enable the user to

capacitively decouple the bandgap reference for very

low output noise (down to 50µVrms).

Notes:

(1) Where X denotes voltage options - see table on

page 5.

Package

MSOP-10

The devices utilize CMOS technology to achieve very

low operating currents (typically 150µA with both out-

puts supplying 150mA). The dropout voltage is typically

165mV at 150mA, helping to prolong battery life. In

addition, the devices are guaranteed to provide 400mA

of peak current for applications which require high initial

inrush current. They have been designed to be used

with low ESR ceramic capacitors to save cost and PCB

area.

(2) Only available in tape and reel packaging. A reel

contains 2500 devices.

The SC1452 comes in the low profile 10-lead MSOP

package.
