PQ5RS1A Datasheet, PDF (1/1 Pages) Sharp Electrionic Components – Low Power-Loss Voltage Regulator

PQ5RS1 series Low Power-Loss Voltage Regulator
0.15A Output, High Cost Performance Type Low Power-Loss Voltage Regulator
(Built-in Reset Signal Generating Function)
General Description
Sharp's PQ5RS1 series is 0.15A output, high cost performance
type low power-loss voltage regulator with built-in reset signal
generating function.
It is applicable to the malfunction prevention of microcomputers
when power supplies of various electronic equipment(AV, OA
equipment) are turned-on or out of order.
Features
(1) Built-in reset signal generating function
(7 series of reset threshold voltage are available.)
(2) Low power-loss
(Dropout voltage: MAX. 1.2V at Io=0.1A)
(3) Compact resin full-mold package(equivalent to TO-220)
(4) High precision output type
(Output voltage precision: ±3.0%)
(5) Overcurrent protection, overheat protection function
Applications
(1) Power supplies for various electronic equipment such as
AV, OA equipment
