LDO voltage regulator

Overview

The voltage regulator consists of a differential amplifier which compares reference voltage with voltage from a feedback divider. It adjusts the impedance of a pass PMOS transistor for stabilization of output voltage at a set level. The output voltage adjustment is defined by the digital code OV<1:0>. It is able to change a feedback divider transfer ratio in range of 0.6 / 0.7 / 0.8 / 0.9.
The block is fabricated on TSMC SiGe BiCMOS 0.18 um technology.
