... Low-Dropout, 120mA Linear Regulators ______________________________________________________________Pin Description PIN NAME Active-Low Shutdown Input. A logic low reduces the supply current to 0.1nA. On the MAX8864, a logic low 1 SHDN also causes the output voltage to discharge to GND. Connect to IN for normal operation. Ground. This pin also functions as a heatsink. Solder to large pads or the circuit board ground plane to max- ...

... The output can be shorted to ground for an indefinite time period without damaging the part. Thermal overload protection limits total power dissipa- tion in the MAX8863/MAX8864. When the junction tem- perature exceeds T sends a signal to the shutdown logic, turning off the pass transistor and allowing the IC to cool. The thermal sensor will turn the pass transistor on again after the IC’ ...

... In battery-powered systems, this will deter- mine the useful end-of-life battery voltage. Because the MAX8863/MAX8864 use a P-channel MOSFET pass transistor, their dropout voltage is a function of R multiplied by the load current (see Electrical Characteristics ) ...
