... LDO Regulation and Programmable Output Divider The LDO Regulator is implemented with a high-gain operational amplifier driving a PMOS pass transistor. The design of the ISL9011A provides a regulator that has low quiescent current, fast transient response, and overall stability across all operating and load current conditions. ...
