ABSTRACT:
A reverse current limited circuit configured to provide a reverse current limited low dropout voltage output. The reverse current limited circuit, coupled between a pair of terminals, comprises (i) a MOS pass transistor coupled in series between the first and second terminals, (ii) connection circuitry to connect the substrate of the MOS pass transistor to either one of the pair of terminals based on the relative magnitudes of the voltages measured on the pair of terminals, (iii) activation circuitry for turning on and off the MOS pass transistor based on the relative magnitudes of the voltages measured on the pair of terminals and (iv) comparison circuitry used to compare the voltages of the pair of terminals and to control the activation circuitry and the connection circuitry in response to the comparison made.
