IN
Regulator Input. Supply voltage can range from -2.5V to -6.5V. Bypass with a 1
μ
F capacitor to GND
(see
Capacitor Selection
and
Regulator Stability
). This pin also functions as a heatsink. Solder to a
large PC board pad or directly to the PC board power plane to maximize thermal dissipation.
Shutdown Input. Drive
SHDN
to GND to turn the regulator off, reducing the input current to less than
1nA. Drive
SHDN
above +1.6V or below -1.6V to enable the regulator. Connect
SHDN
to IN for
always-on operation.
Dual Mode
Regulator Feedback Input. Connect SET to GND for the preset output voltage. Use a
resistive voltage-divider from OUT to SET to set the output voltage between -1.25V and -5.5V.
Regulation setpoint is -1.25V.
Regulator Output. OUT supplies up to 200mA in regulation. Bypass to GND with a 1
μ
F ceramic
capacitor.
