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
cess, the LP2986 delivers superior performance:
Dropout Voltage: Typically 180 mV
mV
Ground Pin Current: Typically 1 mA
200 µA
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.
