Features 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. 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% 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.

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(10µA) if it’s more than VO1- 0.2V. The equations of delay time is same as below. Trd = (Cd X 2.5) / 10µA 2. These parameters, although guaranteed, are not 100% tested in production. 10-SIP H/ S PACKAGE OUTLINE DIMENSIONS 0.984 (TYP) 25.00 (TYP) 0.1575 ± 0.0055 4.00 ± 0.15 0.472 (TYP) 12.00 (TYP) 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) 0.100 (TYP) 2.540 (TYP) 0.018 ± 0.004 0.45 ± 0.10 1.016 ± 0.008 25.8 ± 0.20 Inches ( mm ) ORDERING NUMBER GM 7631 SIP10 T Shipping T: Tube Circuit Type Package SIP10: 10- SIP H/ S GM7631 Gamma Micro. 5 6 GM7631
