LP2950/LP2951 150mA Low Drop Out Voltage Regulators

FEATURES

l Output accuracy 5V, 150mA output

l Very low quiescent current

l Low dropout voltage

l Extremely tight load and line regulation

l Very low temperature coefficient

l Need only 1µF for stability

l Unregulated DC input can withstand -20V reverse

battery and +60V positive transients

l Direct replacement for LP2950/LP2951 sockets

TO-92

The LP2950 and LP2951 are

low power voltage regulators. These

devices are an excellent choice for

use in battery powered applications

such as cordless telephone, radio

control

systems,

and

portable

computers.

The

LP2950

and

LP2951

feature very low quiescent current

(75

µA Typ.) and very low drop

output voltage (Typ. 40

µV at light

load and 380mV at 100mA). This

includes a tight initial tolerance of

0.5% typ., extremely good load and

PRODUCT DESCRIPTION

line regulation 0.05% typ. and very

low output temperature coefficient,

making the LP2950/LP2951 useful

as a low power voltage reference.

Other key additional feature of this

unregulated input voltage transient of

-20V below ground (reverse battery).

The error flag output feature is

used as power-on reset for warn of a

low output voltage, due to following

batteries on input. Other feature is

the logic compatible shutdown input

which enabled\s the regulator to be

switched on and off. The LP2950 is

offered in 3-pin TO-92 package

compatible

with

other

5

volt

regulators. The LP2951 is available

in 8-pin plastic, SOP-8 package.

The regulator output voltage

may be pin-strapped for a 5 volt of

programmed from 1.24 volt to 29

volts with external pair of resistors.

Using of as design, processing and

testing techniques make our LP2950

and LP2951 superior over similar

products.
