... Smart thermal shutdown protects the device against overheating. Power Control The ISL9001A has an enable pin (EN) to control power to the LDO output. When EN is low, the device is in shutdown mode. During this condition, all on-chip circuits are off, and the device draws minimum current, typically less than 0.1μ ...

... 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 ISL9001A provides a regulator that has low quiescent current, fast transient response, and overall stability across all operating and load current conditions. ...
