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.

cess, the LP2986 delivers superior performance:

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.
