Description :

www.fairchildsemi.com KA7632/KA7633 Fixed Multi-output Regulator Features • Output Currents up to 0.5A (output1 & 2) • Output Current up to 1A with External Transistor (output3) • Fixed Precision Output 1 voltage 3.3V ± 2% • Fixed Precision Output 2 voltage 8V ± 2% (KA7632) • Fixed Precision Output 2 voltage 9V ± 2% (KA7633) • Control Signal Generator for Output 3 voltage (5.1V ± 2%) • Reset Facility for Output Voltage1 • Output 2,3 with Disable by TTL Input • Current Limit Protection at Each Output • Thermal Shut Down Description The KA7632/KA7633 is a multi-output positive voltage regulator designed to provide fixed precision output voltages of 3.3V, 8V (KA7632) / 9V (KA7633) at current up to 0.5A and 5.1V at current up to 1A with external PNP transistor. An internal reset circuit generates a reset pulse when the output 1 decrease below the regulated value. Output2 & 3 can be disabled by TTL input. Protection features include over voltage protection, short circuit protection and thermal shutdown. 10-SIP H/S Internal Block Diagram Vin1 1 10uA 3 Cd 100nF RESET Vsys 6 + SW Thermal Shut Down Bandgap Reference Vin2 2 OVP Vin1 2.5V DEL.CAP + SCP 9 Output 1 + 50mV OVP Vin2 10K A614 “Y” Control 10 Output3 7 + SCP + + Output 2,3 1.4V SCP 8 Output 2 5 GND 4 Disable Rev. 1.0.1 ©2001 Fairchild Semiconductor Corporation KA7632/KA7633 Absolute Maximum Ratings Parameter DC Input Voltage Disable Input Voltage Output Current Power Dissipation Junction Temperature Operating Temperature Symbol Vin Vc Io Pd Tj Topr Value 20 20 0.5 1.5 +150 0~+125 Unit V V A W °C °C Remark No Heatsink – Electrical Characteristics(KA7632) (Refer to test circuit Vin1=6V ,Vin2=10.5V ,Tj = +25 °C, unless otherwise specified) Parameter Output Voltage 1 Symbol Vo1 Conditions Io1=10mA 6V
