TO-252-5L
SN278Rxxx
Low Dropout Voltage Regulator (2.0A Series)
Description
The SN278Rxx is an efficient linear low dropout voltage regulator for
various electronic equipment. It is designed to provide very low dropout
voltage, and better than 2.5% output voltage accuracy.
And the SN278Rxx has various key features such as current limiting,
over temperature shut-down, over voltage protection, enable pin, and
low noise performance with an low noise option.
Furthermore, it is available in adjustable or fixed output voltages in
TO-252-5L, TO-220F-4SL packages.
TO-220F-4SL
Application
◈ Consumer and personal electronics
◈ SMPS post-regulator / dc-to-dc modules
◈ High-efficiency linear power supplies
