GM7631

Description The GM7631 is a multi-output positive voltage regulator, designed to provide fixed precision output voltages of 5.1V, 9V at current up to 0.5A and 12V 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. 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 9V ± 2% 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 TYPICAL APPLICATION GM7631 1 VIN 1 VIN 2 Active "H" Disable RESET 2 3 Cd 4 5 6 7 8 Contorl 9 10 Output3 GND Output 2 Output 1 10K www.gammamicro.com GM7631 V0.1 1 Vsys MARKING INFORMATION & PIN CONFIGURATIONS (TOP VIEW) GM7631 AYWW VIN 1 VIN 2 DEL.CAP Disable GND Output 3 Output 1 Output 2 Control RESET A Y WW = Assembly Location = Year = Weekly ORDERING INFORMATION O rdering Number G M7631SIP10T Package 10- SIP H/ S Shipping 20 Units/ Tube * For detail Ordering Number identification, please see last page.
