TYPICAL PERFORMANCE CHARACTERISTICS
OUT (Pin 1): Reference Output. The output can source
up to 10mA and sink up to 2mA. It is stable with output
bypass capacitor ranging from 0μF to 1μF .
IN (Pin 2): Positive Supply. Bypassing with a 0.1μF ca-
pacitor is recommended if the output loading changes.

DNC (Pin 3): (LTC1258-2.5/LTC1258-3/LTC1258-4.1/
LTC1258-5) Do Not Connect. Connected internally for post
package trim. This pin must be left unconnected.
