LP8340
Low Dropout, Low I
Q
, 1.0A CMOS Linear Regulator
General Description
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.
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.
