AP78LXX SERIES 3-TERMINAL POSITIVE REGULATORS AP78L05/08/12 Document number: DS31054 Rev. 11 - 4 2 of 16 www.diodes.com August 2021 © Diodes Incorporated OBSOLETE – PART DISCONTINUED Typical Application Circuit Fixed Output Regulator AP78Lxx OUTIN Input Output GNDC1 0.33µF 0.1µF (†) Required if the regulator is located more than 3” from the power supply filter (‡) See Note 5 in the electrical characteristics table Pin Descriptions Pin Name Description VIN Operating Voltage Input VOUT Voltage Output Pin GND Ground NC No Connection Functional Block Diagram 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.
