LP2950/LP2951 150mA Low Drop Out Voltage Regulators

PRODUCTDESCRIPTION

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

(75µA Typ.) and very low drop

output voltage (Typ. 40µV at light

load and 380mV at 100mA). This

includes a tight initial tolerance of

0.5% typ., extremely good load and

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).

switched on and off. The LP2950 is

offered in 3-pin TO-92 package

compatible with other

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.

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
