PIN FUNCTIONS
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.
(VOUT + 0.2V) ≤ VIN ≤ 12.6V.
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.
FB (Pin 3): (LT1258) Resistor Divider Feedback Pin. Con-
nect a resistor divider from OUT to GND and the center
tap to FB. This pin sets the output potential.

.;R1 is connected from OUT to
FB and R2 from FB to GND.
GND (Pin 4): Negative Supply or Ground Connection.
DNC (Pins 5, 6, 7, 8): Do Not Connect. Connected in-
ternally for post package trim. These pins must be left
unconnected.
