Low Power-Loss Voltage Regulators
PQ05SZ5/PQ05SZ1 Series
PQ05SZ5/PQ05SZ1 Series
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 VO-I=<13V)
