A low power programmable low drop-out regulator capable of providing 1V output has been proposed.The regulator requires a supply voltage of 1.2V and works in the temperature range of -40 to 125 ˚C in nominal corner (i.e, normal doping for PMOS and NMOS Field Effect Transistors), yielding a load regulation of 3%.The output voltage level is controlled externally by means of 2 1-bit control signals.The circuit provides a DC gain of 30 dB and a maximum DC Power Supply Rejection Ratio of -35 dB and a worst case PSRR of -20 dB.Power dissipation in the load is nearly 100 µW.
