PQ07VR5MAZ Low Power-loss Voltage Regulator
Low Power-loss Voltage Regulator with Reset Function in Detecting Input Voltage Drop
General Description
Sharp's PQ07VR5MAZ is a compact, surface mount, 0.5 A
output type low power-loss voltage regulator with reset signal
output function in detecting input voltage drop.
It is suitable for malfunction prevention of microcomputers in
various electronic equipment such as AV, OA equipment
when it is turned-on or it is in error of operation.
Features
(1) Reset signal generating function.
(The reset detection voltage can be custom-ordered in
the range of 3.5 V to 4.5 V.)
(2) Low power-loss
(Dropout voltage : Max. 0.5 V at Io=0.3 A)
(3) Compact, surface mount package.
(Equivalent to SC-63.)
(4) Output voltage variable type (1.5 V to 7.0 V)
(5) Overcurrent protection and overheat protection function.
(6) Tape-packaged products and sleeve-packaged products
are available.
Applications
(1) Power supplies of AV, OA equipment, and various
electronic equipment
(2) CD-ROM drives and CD-R drives
(3) DVD-ROM drives
