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.
The ISL80136 offers adjustable output voltages from 2.5V to
12V. It features an EN pin that can be used to put the device
into a low-quiescent current shutdown mode where it draws
only 1.8µA of supply current. The device features overtemperature shutdown and current limit protection.
The ISL80136 is rated over the -40°C to +125°C temperature
range and is available in an 8 lead EPSOIC with an exposed
pad package.
