Overview

LP8340 Low Dropout, Low IQ, 1.0A CMOS Linear Regulator October 2003 LP8340 Low Dropout, Low IQ, 1.

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 420mV Typical Dropout @ 1.0A (VO = 5V) Wide Operating Range 2.7V to 10V Internal 1.0A PMOS Output Transistor 19µA Typical Quiescent Current Thermal Overload Limiting Foldback Current Limiting Z.
