| Under development New product 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. Outline Dimensions 6.6MAX 5.20.5 3 (Unit: mm) 2.30.5 (0.5) 9.7MAX 5.50.5 (1.7) 0.5+0.2 -0.1 (0 to 0.25) 2.5MIN 4-(1.27) (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 (Ta=25C) Symbol Rating Unit Parameter *1 Input voltage V VIN 10 V Output voltage adjustment terminal voltage Vadj 7 *1 Reset output voltage V Vr 10 Output current A IO 0.5 Reset output current mA Ir 5 Power dissipation (no heat sink) PD W 0.8 C Junction temperature Tj 150 *2 Operating temperature Topr -20 to +80 C Tstg -40 to +150 C Storage temperature Soldering temperature Tsol 260(For 10s) C *1 All are open except GND and applicable terminals. *2 Overheat protection may operate at T = 125 to 150C.
