The LND2951 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 (75A 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 logiccompatible 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 pinstrapped 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.
