LP8345 Low Dropout, Low IQ, 500mA CMOS Linear
Regulator
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 ...
