The ISL80138 is a high voltage, adjustable V_OUT 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 to operate across the -40°C to +125°C temperature range and is available in a 14 lead HTSSOP with an exposed pad package.
