Introduction
The AP78LXX series is a three terminal device with fixed output voltages from 5V,8V and 12V. The AP78LXX fixed voltage
regulator series has built-in thermal overload protection which prevents the device from being damaged due to excessive
junction temperature. The regulator also contains internal short-circuit protection which limits the maximum output current, and
safe-area protection for the pass transistor which reduces the short-circuit current as the voltage across the pass transistor is
increased.
