FUNCTION
Ground
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.
