Low Power-Loss Voltage Regulators

PQ05SZ5/PQ05SZ1 Series

PQ05SZ5/PQ05SZ1 Series

Low Power-Loss Voltage Regulators (Built-in Reverse Voltage Protection Function)

■ 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)

■ Applications

¡Portable equipment

¡Notebook PC
