Features
PQ15RW21
Low Power-Loss Voltage Regulator
2.0A, Variable Output, General Purpose Type Low Power-Loss Voltage Regulator
SHARP's
PQ15RW21
is 3.0 to 15V/2.0A output type
general purpose low power-loss voltage regulator(TO-220).
It contributes to energy and space saving of various
electronic equipment such as AV, OA equipment.
(1) Low power-loss
(Dropout voltage: MAX. 0.5V at Io=2A)
(2) 2A output type
(3) Compact resin mold package(equivalent to TO-220)
(4) Variable output voltage(3.0 to 15V)
(5) Output voltage precision:
2.5%
(6) Overcurrent, overheat protection functions
(7) Lead forming type is also available.
Tec.PW961004
Applications
(1) Power supplies for various electronic equipment such
as AV, OA
