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.

(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.

(1) Power supplies of AV, OA equipment, and various

electronic equipment

(2) CD-ROM drives and CD-R drives

(3) DVD-ROM drives
