ISL78301集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

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.
