40V, Low Quiescent Current, 50mA Linear Regulator
ISL80136
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 over-
temperature 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.

Electrical Specifications Recommended Operating Conditions, unless otherwise noted. VIN = 14V, IOUT = 1mA, TA = TJ = -40°C to
+125°C, unless otherwise noted. Typical specifications are at TA = +25°C. Boldface limits apply across the operating temperature range, -40°C to
+125°C. (Continued)

NOTES:
6. Dropout voltage is defined as (VIN - VOUT) when VOUT is 2% below the value of VOUT.
7. Enable to Regulation is the time the output takes to reach 95% of its final value with VIN = 14V and EN is taken from VIL to VIH in 5ns. The output
voltage is set at 5V.
8. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
