GENERAL DESCRIPTION

The AMS2950 and AMS2951 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

150mA) thus prolonging battery life. The quiescent current increases only slightly in dropout. The AMS2950/AMS2951 has

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

The AMS2950 and AMS2951 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 AMS2950 is offered in the 3-pin TO-92 package. AMS2951 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 AMS2951 also features the logic-compatible shutdown input which enables the regulator to be switched on and

off. The AMS2951 device may be pin-strapped for a 5.0V, 3.3V, 3.0V or 2.5 output, or programmed from 1.24V to 29V with

an external pair of resistors.
