LP8345 Low Dropout/ Low IQ/ 500mA CMOS Linear Regulator

The LP8345 low-dropout CMOS linear regulator are available in 5V, 3.3V, 2.5V, 1.8V or adjustable output versions. Packaged in our 6ld LLP package and 3ld DPAK they can deliver up to 500mA output current. Typical dropout voltage @ 500mA is 210mV for the 5.0V version, 270mV for the 3.3V version and 33.

LP8345 Features

* a PMOS output transistor which unlike PNP type low dropout regulators requires no base drive current. This allows the device ground current to remain less than 50µA over operating temperature, supply voltage and irrespective of the load current. Features n n n n n n n n n n ± 1.5% Typical VOUT tol
