LP8340

Low Dropout, Low I_Q, 1.0A CMOS Linear Regulator

General Description

Features

1.5% Typical V_OUTtolerance

The LP8340 low-dropout CMOS linear regulator is available

in 5V, 3.3V, 2.5V, 1.8V and adjustable output versions. Pack-

aged in the 6ld LLP package and 3ld DPAK. The LP8340 can

deliver up to 1.0A output current.

n 420mV Typical Dropout 1.0A (V_O= 5V)

n Wide Operating Range

2.7V to 10V

n Internal 1.0A PMOS Output Transistor

n 19µA Typical Quiescent Current

n Thermal Overload Limiting

n Foldback Current Limiting

n Zener Trimmed Bandgap Reference

n Space saving LLP package

n Temperature Range

Typical dropout voltage is 420mV at 1.0A for the 5.0V ver-

sion, 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.
