The AMS2954 series are micropower voltage regulators ideally suited for use in battery-powered systems. These devices feature very low quiescent current (typ.75A), and very low dropout voltage (typ.50mV at light loads and 380mV at 250mA) thus prolonging battery life. The quiescent current increases only slightly in dropout. The AMS2954 has positive transient protection up to 60V and can survive unregulated input transient up to 20V below ground. The AMS2954 was 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 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, 2.5, 3.0V, 3.3V or 5V output, or programmed from 1.24V to 29V with an external pair of resistors.
