GENERAL DESCRIPTION

The AMS2942 are micropower voltage regulators ideally suited for use with high voltage powered systems. This device feature very low quiescent current (typ.130µA), and very low dropout voltage (typ.45mV at light loads and 380mV at 100mA). The quiescent current increases only slightly in dropout. The AMS2942 has positive transient protection up to 60V and can survive unregulated input transient up to 20V below ground.
