General Description

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 335mV for the 2.5V version.

The devices include a zener trimmed bandgap voltage reference, foldback current limiting and thermal overload limiting.

The 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

±1.5% Typical V_OUTtolerance
210mV Typical Dropout @ 500mA (V_O = 5V)
Wide Operating Range	2.7V to 10V
Internal 500mA PMOS Output Transistor
19µA Typical Quiescent Current
Thermal Overload Limiting
Foldback Current Limiting
Zener Trimmed Bandgap Reference
Space saving LLP package

Temperature Range
