Pin Functions

PIN TYPE DESCRIPTION
NAME NO.
ADJ/EN 1 I This pin connects to the reference voltage. A low signal disables the IC and a high signal enables the IC. Connected the voltage reference directly or with a voltage divider for lower output voltages. To compensate for line influences, TI recommends to place a capacitor close to the IC pins.
GND 2 G Internally connected to pin 5
5 Internally connected to pin 2
VIN 3 I This pin is the IC supply. To compensate for line influences, TI recommends to place a capacitor close to the IC pins.
VOUT 4 O VOUT is an external capacitor that is required between VOUT and GND with respect to the capacitance and ESR requirements given in the Recommended Operating Conditions.
