FMR7632 500mA 20V Fixed Multi-Output Regulator Fixed Multi-output Regulator 10-SIP H / S DESCRIPTION The FMR7632 is a multi-output positive voltage regulator designed to provide fixed precision output voltages of 3.3V, 8V 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. Output 2 & 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(10 A) if it’s more than Vo1- 0.2V. The equations of delay time is same as below. Trd = (Cd x 2.5) / 10 µA 2.
