Abstract
A linear power supply () includes a P-channel (or PNP) first output transistor () connected between an input terminal of an input voltage (Vin) and an output terminal of an output voltage (Vout), an N-channel (or NPN) second output transistor () connected in parallel to the first output transistor (), and a control circuit () that switches between a first mode and a second mode according to the input voltage (Vin), in which the first mode uses the first output transistor () while the second mode uses the second output transistor () as an output transistor that generates the output voltage (Vout) from the input voltage (Vin).
