UC1524A UC2524A UC3524A is a kind of integrated circuit (IC) with a precise 5V voltage reference and error amplifier, which can be applied to the output lines of the power supply.
This document provides technical specifications for the Unitrode UC1524A family of regulating PWM ICs, which are fully interchangeable with the standard UC1524 family. Key features include a precision 5V reference internally trimmed to +1%, high-performance current limit function, and under-voltage lockout with hysteretic turn-on.
