Application Hints

INPUT CAPACITOR

An input capacitor whose capacitance is

≥ 1 µF is required

between the LP2980 input pin and ground (the amount of

capacitance may be increased without limit).

The input capacitor must be located a distance of not more

than 1 cm away from the input pin and returned to a clean

analog ground. Any good quality ceramic, Tantalum, or film

capacitor may be used at the input.

IMPORTANT: Tantalum capacitors may suffer catastrophic

failure due to surge current when connected to a low-

impedance source of power (like a battery or very large
