General Description
Sharp's
PQ05RD21 series
is 2.0A 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.
(1) Low power-loss(Dropout voltage: MAX 0.5V at Io=2.0A)
(2) 2.0A output type
(3) Compact resin full-mold package(equivalent to TO-220)
(4) Available 3.3V/5V/9V/12V output type
(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.
Features
Applications
(1) Power supplies for various electronic equipment
such as AV, OA
