| Description The GM7630 is a multi-output positive voltage regulator, designed to provide fixed precision output voltages of 5.1V, 8V 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 8V 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 GM7630 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 GM7630 V0.1 1 Vsys MARKING INFORMATION & PIN CONFIGURATIONS (TOP VIEW) GM7630 AYWW VIN 1 VIN 2 DEL.CAP Disable GND Output 3 Output 1 Output 2 Control RESET A Y WW = Assembly Location = Year = Work Week ORDERING INFORMATION Ordering Number GM7630SIP10T Package 10- SIP H/ S Shipping 20 Units/ Tube * For detail Ordering Number identification, please see last page.

To check the reset circuit ,the reset output is low to discharge the delay capacitor(=Cd). if it's less than VO1-0.25V. And the reset output is high when the delay capacitor voltage linearly increased by the interal current source(10A) if it's more than VO1- 0.2V. The equations of delay time is same as below. Trd = (Cd X 2.5) / 10A 2. These parameters, although guaranteed, are not 100% tested in production. 10-SIP H/ S PACKAGE OUTLINE DIMENSIONS 0.984 (TYP) 25.00 (TYP) 0.472 (TYP) 12.00 (TYP) 0.1575 0.0055 4.00 0.15 0.5905 0.0055 15.0 0.15 0.4725 0.0115 12.0 0.30 0.331 0.006 8.40 0.15 0.024 0.004 0.60 0.10 0.236 (MIN) 6.000 (MIN) 0.02 0.004 0.50 0.10 0.047 (TYP) 1.200 (TYP) 1.016 0.008 25.8 0.20 0.100 (TYP) 2.540 (TYP) 0.018 0.004 0.45 0.10 Inches ( mm ) ORDERING NUMBER GM 7630 SIP10 T Gamma Micro.
