LP2975 MOSFET LDO Driver/Controller
September 1997
LP2975
MOSFET LDO Driver/Controller
General Description
A high-current LDO regulator is simple to design with the
LP2975 LDO Controller. Using an external P-FET, the
LP2975 will deliver an ultra low dropout regulator with ex-
tremely low quiescent current.
High open loop gain assures excellent regulation and ripple
rejection performance.
The trimmed internal bandgap reference provides precise
output voltage over the entire operating temperature range.
Dropout voltage is 鈥渦ser selectable鈥?by sizing the external
FET: the minimum input-output voltage required for opera-
tion is the maximum load current multiplied by the R
DS
(ON)
of the FET.
Overcurrent protection of the external FET is easily imple-
mented by placing a sense resistor in series with V
IN
. The
57 mV detection threshold of the current sense circuitry mini-
mizes dropout voltage and power dissipation in the resistor.
The standard product versions available provide output volt-
ages of 12V, 5V, or 3.3V with guaranteed 25藲C accuracy of
1.5% (鈥淎鈥?grade) and 2.5% (standard grade).
