Low Noise, High PSRR, Replica LDO
The WEALDORP1812NI08SFN22M22G is a voltage regulator operating from 1.8 V and 1.2 V power supplies.
Overview
The WEALDORP1812NI08SFN22M22G is a voltage regulator operating from 1.8 V and 1.2 V power supplies. The WEALDORP1812NI08SFN22M22G provides two 0.8 V outputs. The outA output has double current driving capability compared to outB. Due to poor dc-line regulation the accuracy of the output voltage can be calibrated through a 4 bit binary control when the load current varies under a wide range.
