Description
Internal device power and voltage sense input. This dual function input provides both feedback
voltage sensing and internal chip power. It should be connected to the regulator output. (See
Section 4.0, Applications).
Power supply voltage input.
Shutdown input. A logic low on this input suspends device operation and suppl y current is
reduced to less than 0.5 μ A. The device resumes normal operation when SHDN is again brought
high. An RC circuit connected to this input also determines the soft-start time.
Ground terminal.
External switch transistor drive complimentary output. This pin drives the external switching
transistor. It may be connected to the base of the external bipolar transistor or gate of the external
N-channel MOSFET. (See Section 4.0, Applications).
