LP8345
Low Dropout, Low IQ, 500mA CMOS Linear Regulator
General Description
The LP8345 low-dropout CMOS linear regulator are avail-
able 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 ref-
erence, foldback current limiting and thermal overload limit-
ing.
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.
