Description

The KA7630/KA7631 is a multi-output positive voltage regulator designed to provide fixed precision output voltagesof 5.1V, 8V (7630) / 9V(7631) at current up to 0.5Aand 12Vat current up to 1A with external PNP transistor.

An internal reset circuit generates a reset pulse when theoutput 1 decreases below the regulated value. Output2 & 3can be disabled by TTL input. Protection features includeover voltage protection, short circuit protection and thermal shutdown.

Notes:

1. To check the reset circuit ,the reset output is low to discharge the delay capacitor(=Cd). it’s less than Vo1-0.25V. And the

reset output is high when the delay capacitor voltage linearly increased by the internal current source(10µA) if it’s more thanVo1- 0.2V. The equation of delay time is same as below. Trd = (Cd×2.5) / 10µA2. These parameters, although guaranteed, are not 100% tested in production.
