Datasheet for the APL5336, a 536 KB PDF. Anpec uses the APL prefix for its power management ICs, and this part is a linear regulator of the type often found supplying DDR termination or low-voltage rails on motherboards. The document lists pin functions, package outline, enable logic and typical application values, so a technician can verify input, output and enable voltages when a rail is missing or low. Match the marking on the chip with the code in the datasheet before replacing it.
