LP2986
Micropower, 200 mA Ultra Low-Dropout Fixed or
Adjustable Voltage Regulator
General Description
The LP2986 is a 200 mA precision LDO voltage regulator
which offers the designer a higher performance version of
the industry standard LP2951.
Using an optimized VIP
(Vertically Integrated PNP) pro-
cess, the LP2986 delivers superior performance:
Dropout Voltage:
Typically 180 mV
@
200 mA load, and 1
mV
@
1 mA load.
Ground Pin Current:
Typically 1 mA
@
200 mA load, and
200 μA
@
10 mA load.
Sleep Mode:
The LP2986 draws less than 1 μA quiescent
current when shutdown pin is pulled low.
Error Flag:
The built-in error flag goes low when the output
drops approximately 5% below nominal.
Precision Output:
The standard product versions available
can be pin-strapped (using the internal resistive divider) to
provide output voltages of 5.0V, 3.3V, or 3.0V with guaran-
teed accuracy of 0.5% (“A” grade) and 1% (standard grade)
at room temperature.
