LND2950 / LND2951
GENERAL DESCRIPTION
High accuracy output voltage
Guaranteed 100mA output
Very low quiescent current
Low dropout voltage
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
FEATURES
The LND2950-XX is a low power voltage
regulator.This device is an excellent choice for use in
battery powered application such as cordless
telephone, radio control systems, and portable
computers.
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.
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.
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.
