AMS2930 series consists of positive fixed and adjustable voltage regulators ideally suited for use in battery-powered systems. These devices feature very low quiescent current of 1mA or less when supplying 10mA loads. This unique characteristic and the extremely low input -output differential required for proper regulation (0.2V for output currents of 10mA) make the AMS2930 ideal to use for standby power systems. Originally designed for automotive applications, the AMS2930 and all regulated circuitry are protected from input fault conditions caused by reverse battery installation or two battery jump starts. During line transients, such as load dump (60V) when the input voltage to the regulator can momentarily exceed the specified maximum operating voltage, the regulator will automatically shut down to protect both internal circuits and the load. The AMS2930 series also includes internal current limiting, thermal shutdown, and is able to withstand temporary power-up with mirror-image insertion. The AMS2930 is offered in the 3-pin TO-92 package, 8-pin plastic SOIC, TO-220 and TO-263 packages. Download Data sheets

LP2950 and LP2951 are micro power voltage regulators ideally suited for use in battery-powered systems. These devices feature very low quiescent current (typ.75?A), 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 2.5V, 3.0V, 3.3V or 5.0V output, or programmed from 1.24V to 29V with an external pair of resistors. Download Data sheets
