ISL80138
40V, Low Quiescent Current, 150mA Linear Regulator
FN7969
Rev 1.00
January 15, 2016
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 to operate across the -40°C to +125°C
temperature range and is available in a 14 lead HTSSOP with
an exposed pad package.
