PRODUCT DESCRIPTION

The AMS2930 series consists of positive fixed and adjustable 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 extremely low input -output differential required for proper regulation (0.2V for output currents of
10mA) make the AMS2930 ideal to use for standby power systems.

Originally designed for automotive applications, the AMS2930 and all regulated circuitry are protected from input fault
conditions caused by reverse battery installation or two battery jump starts. During line transients, such as load dump (60V)
when the input voltage to the regulator can momentarily exceed the specified maximum operating voltage, the regulator will
automatically shut down to protect both internal circuits and the load. The AMS2930 series also includes internal current
limiting, thermal shutdown, and is able to withstand temporary power-up with mirror-image insertion.

The AMS2930 is offered in the 3-pin TO-92 package, 8-pin plastic SOIC, TO-220 and TO-263 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), 50°C/W for the
TO-220 package and 73°C/W for the TO-263 package. If the TO-220 package is used with a heat sink, θJA is the sum of the package thermal resistance junction-to­case of 3°C/W and the thermal resistance added by the heat sink and the thermal interface. The thermal resistance of the TO-263 package can be reduced by
increasing the PCB copper area thermally connected to the package: using 0.5 square inches of copper area, ϕ JA is 50°C/W; with 1 square inch of copper area ϕ JA is
37°C/W; and with 1.6 or more square inches of copper area ϕ JA is 32°C/W.
