Description
1
EXT
Switch transistor control output. This terminal connects to the gate of an external P-channel
MOSFET (or to the base of an external PNP transistor through a current limiting resistor).
Power supply voltage input.
Ground terminal.
Shutdown input (active low). The device enters a low power shutdown state when this input is
brought low. During shutdown, regulator action is suspended, and supply current is reduced to
less than 0.5
μ
A. The device resumes normal operation when SHDN is again brought high.
Voltage sense input. This input senses output voltage for regulation and must be connected to the
output voltage node as shown in the application schematic in this data sheet.
