The ISL80138 is a high voltage, adjustable VOUT low quiescent

current linear regulator ideally suited for “always-on” and “keep

alive” applications. The ISL80138 operates from an input voltage

of +6V to +40V under normal operating conditions and

consumes only 18µA of quiescent current at no load.

The ISL80138 features an EN pin that can be used to put the

device into a low-quiescent current shutdown mode where it

draws only 2µA of supply current. The device features

over-temperature shutdown and current limit protection.

The ISL80138 is rated over the -40°C to +125°C temperature

range and is available in a 14 lead HTSSOP with an exposed pad

package.
