GENERAL DESCRIPTION
The AMS78LXX series consists of positive fixed voltage regulators ideally suited for use in battery-powered systems. These
devices feature very low quiescent current of 1mA or less when supplying 10mA loads. This unique characteristic and the low
input -output differential of less than 1V required for proper regulation, make the AMS78LXX ideal to use for standby power
systems and portable equipment.
The AMS78LXX series also includes internal current limiting, over voltage protection, thermal shutdown, and is able to
withstand temporary power-up with mirror-image insertion.
The AMS78LXX series is offered in the 3-pin TO-92 package, 8-pin plastic SOIC and SOT-89 packages.

Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. For guaranteed performance limits and associated test conditions, see
the Electrical Characteristics tables.
Note 2: See Circuit in Typical Applications. To ensure constant junction temperature, low duty cycle pulse testing is used.
Note 3: Limits appearing in boldface type apply over the entire junction temperature range for operation. Limits appearing in normal type apply for TA = TJ =
25°C.
Note 4: The junction-to-ambient thermal resistance are as follows: 195°C/W for the TO-92 (N) package, 160°C/W for the molded plastic SO-8 (S), 150°C/W for
the SOT-89 package.

**C2 must be at least 10µF to maintain stability; it can be increased without bound to maintain regulation during transients and it should be
located as close as possible to the regulator. This capacitor must be rated over the same operating temperature range like the regulator.
