Design render

How it works

It is a basic LDO Regulator, consisting of a BJT bandgap reference, two OpAmp's, and a pass PMOS transistor.

How to test

Hook up a resistor of 1% 90k resistor to ua_1, as the Iref for the op amp's. Then, ua0 will be the Vout, and ua2 the Vref.

External hardware

A multimeter to measure the output voltages.
