GENERAL DESCRIPTION

The LP2950 and LP2951 are micropower voltage regulators ideally suited for use in battery-powered systems. These devices

feature very low quiescent current (typ.75µA), and very low dropout voltage (typ.45mV at light loads and 380mV at 100mA)

thus prolonging battery life. The quiescent current increases only slightly in dropout. The LP2950/LP2951 has positive

transient protection up to 60V and can survive unregulated input transient up to 20V below ground.

The LP2950 and LP2951 were designed to include a tight initial tolerance (typ. 0.5%), excellent load and line regulation (typ.

0.05%), and a very low output voltage temperature coefficient, making these devices useful as a low-power voltage reference.

The LP2950 is offered in the 3-pin TO-92 package. LP2951 is available in 8-pin plastic SOIC and DIP packages and offers

three major additional system features. An error flag output warns of a low output voltage, often due to failing batteries on

input. The LP2951 also features the logic-compatible shutdown input which enables the regulator to be switched on and off.

The LP2951 device may be pin-strapped for a 5V, 3.3V, or 3V output, or programmed from 1.24V to 29V with an external

pair of resistors.
