PRODUCT DESCRIPTION

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

(Typ. 40㎷ 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 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 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 is offered in 3-pin to-92 package compatible with other

fixed regulator.
