This linear post regulator provides 12 V at 3 A. It employs TL431 reference U1 which, without additional amplification, drives TMOS MTP3055A gate Q1 series pass regulator. Bias voltage is applied through R1 to Q1's gate, which is protected against overvoltage by diode CR1. Frequency compensation for closed-loop stability is provided by C1.Key performance features are: Dropout voltage: 0.6 V Load regulation: 10 mV Line regulation:±5 mV Output ripple: 10 mV pk-pk
