General Description
Sharp's
PQ3RD13
is 3.3V / 1A output type low power-
loss voltage regulator(TO-220).
It contributes to energy and space saving of various
electronic equipment such as AV, OA equipment.
Features
(1) Low power-loss
(Dropout voltage: MAX. 0.5V at Io=0.5A)
(2) 3.3 V ouput
(3) Compact resin full-mold package(equivalent to TO-220)
(4) Low voltage operation(Minimum supply voltage: 3.7V)
(5) Output voltage precision:
3.0%
(6) Built-in ON/OFF control function
(7) Overcurrent, overheat protection functions
(8) Lead forming type is also available.
(PQ3RD13B)
(1) Power supplies for various electronic
equipment such as AV or OA.
