The LP8340 low-dropout CMOS linear regulator is available in 5V, 3.3V, 2.5V, 1.8V and adjustable output versions. Packaged in the 6ld WSON package and 3ld PFM. The LP8340 can deliver up to 1.0A output current.

Typical dropout voltage is 420mV at 1.0A for the 5.0V version, 540mV at 1.0A for the 3.3V version, 670mV at 1.0A for the 2.5V version and 680mV at 800mA for the 1.8V version.

The LP8340 includes a zener trimmed bandgap voltage reference, foldback current limiting and thermal overload limiting.

The LP8340 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.
