description

The V78XX series of switching regulators is

designed as a drop in replacement for 78XX

linear regulators. Because the V78XX series

features high efficiency under all line

conditions, there is no need for a heatsink.

Built-in short-circuit and over-temperature

protections ensure very rugged operations.

Additionally, low ripple and noise

performance makes the parts useful in a wide

range of applications.

1. Vin-Vo>2V, If needed to adjust the output voltage .

2. If the input voltage is above specified then permanent damage may be caused to the device.

3. V7812-500-SMT and V7815-500-SMT are not allowed to operate under no load.
