DESCRIPTION

The LM2950/1 is a low power voltage regulator. This device excellent choice for use in battery powered

application such as cordless telephone, radio control systems, and portable computers.

The LM2950/1 features very low quiescent current (75㎂ Typ.) and very low drop output voltage

(Typ. 400㎷ at light load and 380㎷ at 100㎃).

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 LM2950/1 useful as a low-power voltage reference.

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 enable the

regulator to be switched on and off. The LM2950/1 is available in 8-pin plastic packages.

The regulator output voltage may be pin-strapped for a -XX volt or programmed from 1.24 volt to 29 volts

with external pair of resistors. The LM2950/1 is offered in 3-pin to-92 package compatible with other

fixed regulator.
