VOLTAGE REGULATOR

DESCRIPTION

The UTC 78DXXA family is monolithic fixed voltage regulator

integrated circuit. They are suitable for applications that required

supply current up to 1 A.

FEATURES

* Peak output current up to 1A.

* Fixed output voltage of 3.3V, 4.7V, 5V, 6V, 7V, 8V, 9V, 10V,

12V, 15V, 18V and 24V available.

* Thermal overload shutdown protection.

* Short circuit current limiting.

* Output transistor SOA protection.

Note: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 device is guaranteed to meet performance specifications within 0

3.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.
