78DXXAA
3-TERMINALS 1.5A POSITIVE
VOLTAGE REGULATOR
DESCRIPTION
LINEAR INTEGRATED CIRCUIT
The UTC
78DXXAA
family is monolithic fixed voltage regulator
integrated circuit. They are suitable for applications that required
supply current up to 1.5 A.
FEATURES
* Peak output current up to 1.5A.
* Fixed output voltage of 5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V and
18V available.
* Thermal overload shutdown protection.
* Short circuit current limiting.
* Output transistor SOA protection.

Notes: 1. Absolute maximum ratings are stress ratings only and functional device operation is not implied. The
device could be damaged beyond Absolute maximum ratings.
2. The maximum steady state usable output current are dependent on input voltage, heat sinking, lead
length of the package and copper pattern of PCB. The data are showed as electrical characteristics table
represents pulse test conditions with junction temperatures specified at the initiation of test.
