TA8224H

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8224H Multi Output Voltage Regulator For CD Player The TA8224H is voltage regulator IC, designed for compact disc player use, built in 3 outputs and reset circuit. In addition, protection of over voltage, output to GND short and thermal shut down are involved. TA8224H Features · 3 regulated voltage outputs VOUT1 (for µ−com system) .... fixed voltage output : VOUT1 = 5V (typ.) / 100mA (max.) VOUT2 (for servo system) ...... fixed voltage output : VOUT2 = 5V (typ.) / 300mA (max.) VOUT3 (for driver) ................. adjustable voltage output : VOUT3 = 8V (typ.) / 1.2A (max.) · Built−in reset circuit ................ 2 input, 1 output : Reset sense voltage VR ≤ 3.4V (Ta = 25°C) · Built−in stand−by circuit : STB1 for VOUT1, VOUT2, VOUT3 : STB2 for VOUT2, VOUT3 · Built−in various protection circuits : Over voltage, output to GND short, thermal shut down · Input operating voltage range : VIN (opr) = 7.5~20V : VIN (opr) = 7.5~24V (operating VOUT1 only) Weight: 4.04g (typ.) 1 2002-10-30 Block Diagram TA8224H Explanation For Each Terminal Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 Symbol STB1 GND STB2 Vref Reset1 VOUT3 VIN1 VOUT2 Reset2 VOUT1 VIN2 Reset Function Stand-by switch for VOUT1, VOUT2, VOUT3 GND Stand-by switch Reference for VOUT3 Reset input 1 Adjustable voltage output Input terminal 1 5V output Reset input 2 5V output Input 2 Reset output Remarks GND terminal for bias circuit.
