DATA SHEET

LND2950 / LND2951

100mA Low Dropout Voltage Regulators

GENERAL DESCRIPTION

FEATURES

The LND2950-XX is a low power voltage

•

High accuracy output voltage

Guaranteed 100mA output

Very low quiescent current

regulator.This device is an excellent choice for use in

battery powered application such as cordless

telephone, radio control systems, and portable

computers.

Low dropout voltage

The LND2950-XX/LND2951-XX features very low

quiescent current (75µA Typ.) and very low drop

output voltage (Typ. 40mV at light load and 380mV at

100mA).This includes a tight initial tolerance of 0.5%

typ., extremely good load and line regulation of

0.05% typ., and very low output temperature

coefficient, making the LND2950-XX/LND2951-XX

useful as a low-power voltage reference.

Extremely tight load and line regulation

Very low temperature coefficient

Needs only 1µF for stability

Error Flag warns of output dropout

Logic-Controlled electronic shutdown

Output programmable from 1.24 to 29V

The error flag output feature is used as power-on

reset, warning of a low output voltage, due to falling

battery voltage on input. Another feature is the logic-

compatible shutdown input, which enables the

regulator to be switched on and off.

APPLICATIONS

8 dip

The LND2951-XX is available in 8 pin plastic

packages. The regulator output voltage may be pin-

strapped for a –XX voltage or programmed from 1.24

volts to 29 volts with an external pair of resistors.

The LND2950-XX is offered in a 3-pin TO-92

package compatible with other fixed regulators.
