Low-dropout-linear-regulator


Posted on Nov 14, 2012

This linear post regulator provides 12 V at 3 A. It employs TL431 reference Ul which, without additional amplification, drives TMOS MTP3055A gate Ql series pass regulator. Bias voltage is applied through Rl to Q1`s gate, which is protected against overvoltage by diode CRl. Frequency compensation for closed-loop stability is provided by Cl.
