40V, Low Quiescent Current, 50mA Linear Regulator

The ISL80136 is a high voltage, low quiescent current linear regulator ideally suited for “always-on” and “keep alive” applications. The ISL80136 operates from an input voltage of +6V to +40V under normal operating conditions, consuming only 18µA of quiescent current at no load.
