Abstract:
A method, an apparatus, and a computer program product are provided. The apparatus may be a regulator circuit. The regulator circuit includes a first voltage regulator to regulate a first input voltage to the first voltage regulator, the first voltage regulator including a P-type metal-oxide-semiconductor (PMOS), a second voltage regulator to regulate a second input voltage to the second voltage regulator, and a switch circuit to selectively activate at least one of the first voltage regulator or the second voltage regulator. In one aspect, the second voltage regulator includes an N-type metal-oxide-semiconductor (NMOS). In one aspect, the second voltage regulator comprises a two-stage operational transconductance amplifier (OTA) circuit. In an aspect, the first voltage regulator is coupled to the second voltage regulator.
