The PQ05RA1/PQ05RA11 series are low power loss voltage regulators from SHARP, with output voltages of 5V, 9V, and 12V, and an output current of 1A. The OFF-state leakage current is ≤1μA for switch power supplies, and the power dissipation is PD1 ≤ 1.5W without a heat sink and PD2 ≤ 15W with an infinite heat sink.
This document is a technical datasheet for the SHARP PQ05RA1/PQ05RA11 Series, which are low power-loss voltage regulators. Key features include an OFF-state low dissipation current (approximately 1/10 of the former model), a compact resin full-mold package, and a built-in ON/OFF control function.
| Output current | 1 A |
|---|---|
| Power dissipation (No heat sink) | 15 W |
| Junction temperature | 150 °C |
| Operating temperature | -20 to +80 °C |
| Dropout voltage (MAX) | 0.5 V |
The OFF-state low dissipation current is approximately 1/10 of that of the former model PQOSRF1.
They are suitable for series power supplies in OA and AV equipment such as camcorders and word processors.
