LP2986 Micropower, 200 mA Ultra Low-Dropout Fixed or Adjustable Voltage Regulator

March 2005

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

1 mA load.

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 guaranteed accuracy of 0.5% (“A” grade) and 1% (standard grade) at room temperature.

10 mA load.
