Sharp PQ05RR13, PQ05RR12 Datasheet

Low Power-Loss Voltage Regulators

PQ05RR12/13

1A Output, Low Power-Loss Voltage Regulators(Built-in Reset Signal Generating Function)

PQ05RR12/PQ05RR13

■ Features

¡Compact resin full-mold package
¡Low power-loss (Dropout voltage : MAX. 0.5V)
¡The regulators are provided with reset signal generating function

to prevent errors of microcomputer when input voltage is applied
and output voltage drops.

¡High-precision output type
(Output Voltage precision : ±2.5%) (PQ05RR13)

■ Applications

¡Series power supply for equipment such as TVs, VCRs and

electronic music instruments
