40V, Low Quiescent Current, 150mA Linear Regulator
for Automotive Applications
ISL78301
The ISL78301 is a high voltage, low quiescent current linear
regulator ideally suited for “always-on” and “keep alive”
automotive applications. The ISL78301 operates from an input
voltage of +6V to +40V under normal operating conditions and
operates down to +3V under a cold crank. It consumes only 18µA
of quiescent current at no load on the adjustable version.
The ISL78301 is available in a fixed 3.3V, 5V and adjustable
output voltage (2.5V to 12V) options. It 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 ISL78301 is AEC-Q100 qualified. It is rated over the -40°C to
+125°C automotive temperature range and is available in a
14 Ld HTSSOP with an exposed pad package.

NOTES:
6. Dropout voltage is defined as (VIN - VOUT) when VOUT is 2% below the value of VOUT when VIN = VOUT + 3V.
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. For the
adjustable versions, 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.
