AMS2954 are micro power voltage regulators with very low quiescent current (typ. 75?A), and very low dropout voltage (typ.50mV at light loads and 380mV at 250mA), ideally suited for use in battery-powered systems. The quiescent current increases only slightly at dropout, thus prolonging battery life. The AMS2954 series has positive transient protection up to 60V and can survive unregulated input transient up to 20V below ground. Featuring a tight initial tolerance (typ. 0.5%), excellent load and line regulation (typ. 0.05%), and a very low output voltage temperature coefficient, the AMS2954 can be used as a low-power voltage reference. The AMS2954 is available in the 3L TO-220 package, 3L TO-263, SOT-223, TO-252 and in 8-pin plastic SOIC and DIP packages. In the 8L SOIC and PDIP packages the following additional features are offered: an error flag output warns of a low output voltage, often due to failing batteries on input; the logic-compatible shutdown input enables the regulator to be switched on and off; the device may be pin-strapped for a 2.5V, 3.0V, 3.3V or 5.0V output, or programmed from 1.24V to 29V with an external pair of resistors.
