ISL80410

40V, Low Quiescent Current, 150mA Linear Regulator

OVERVIEW

The ISL80410 is a high voltage, adjustable VOUT , low quiescent current linear regulator ideally suited for “always-on” and “keep alive” applications. The ISL80410 operates from an input voltage of +6V to +40V under normal operating conditions and consumes only 18μA of quiescent current at no load.

The ISL80410 features an EN pin that can be used to put the device into a low-quiescent current shutdown mode in which it draws only 2μA of supply current. The device features over-temperature shutdown and current limit protection.

The ISL80410 is rated to operate across the -40°C to +125°C temperature range and is available in an 8 Ld Small Outline Exposed Pad Plastic Package (EPSOIC).
