process, the LP2986 delivers superior performance:

•

Low Ground Pin Current at All Loads

Dropout Voltage: Typically 180 mV @ 200 mA load,

•

0.5% Output Voltage Accuracy (“A” Grade)

and 1 mV @ 1 mA load.

•

High Peak Current Capability (400 mA Typical)

Ground Pin Current: Typically 1 mA @ 200 mA

•

Wide Supply Voltage Range (16V Max)
