LP8345 Datasheet Low Dropout/ Low Iq/ 500ma CMOS Linear Regulator

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LP8345 Low Dropout, Low IQ, 500mA CMOS Linear Regulator October 2003 LP8345 Low Dropout, Low IQ, 500mA CMOS Linear.

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.

Key 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 tolerance 210mV Typical Dropout @ 500mA (VO = 5V) Wide Operating Range 2.7V to 10V Internal 500mA PMOS Output Transistor 19µA Typical Quiescent Current Thermal Overload Limiting Foldback Current Limiting.
