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
