KA7631集成电路（IC）的线性+开关稳压器规格书PDF中文资料

描述 Description

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

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