Pin No.
(5-Pin SOT-23A)
Symbol
Description
1VOUT
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).
2VDD
Power supply voltage input.
3
SHDN/SS
Shutdown input. A logic low on this input suspends device operation and supply current is
reducedtolessthan0.5
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.
4
GND
Ground terminal.
5
EXT
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).
