Low Power-Loss Voltage Regulators (Built-in Reverse Voltage Protection Function)
s
Features
¡Low
power-loss (Dropout voltage : MAX. 0.5V)
¡Surface
mount type package (Equivalent to SC-63)
¡Built-in
a function to prevent reverse voltage between input and
output
The diode to prevent reverse voltage between input and output is
not necessary. (When V
O-I
=<13V)
