1 / 6 page ©2002 Fairchild Semiconductor Corporation www.fairchildsemi.com Rev. 1.0.1 Features • Output Currents up to 0.5A (Output1 & 2) • Output Current up to 1A with External Transistor (Output3) • Fixed Precision Output 1 Voltage 5.1V ±2% • Fixed Precision Output 2 Voltage 8V ±2% (KA7630) • Fixed Precision Output 2 Voltage 9V ±2% (KA7631) • Control Signal Generator for Output 3 Voltage (12V ±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 KA7630/KA7631 is a multi-output positive voltage regulator designed to provide fixed precision output voltages of 5.1V, 8V (7630) / 9V(7631) at current up to 0.5Aand 12V at current up to 1A with external PNP transistor. An internal reset circuit generates a reset pulse when the output 1 decreases 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 Bandgap Reference + - OVP SCP + - OVP SCP + - + - SCP + - SW Thermal Shut Down Output 2,3 4 8 9 3 6 7 10 5 2 1 1.4V Vsys 10uA Vin1 Vin2 Output 1 Output 2 Disable GND Output3 Control DEL.CAP 100nF A614 "Y" Vin1 Vin2 + - RESET 10K 50mV 2.5V Cd KA7630/KA7631 Fixed Multi-Output Regulator |
