PIN CONFIGURATION
PIN DESCRIPTIONS
SOT23
(DBV)
NAME PIN NO. DESCRIPTION
IN 1 Input supply
GND 2 Ground
Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator into shutdown
EN 3 mode. Refer to the Shutdown section under Applications Information for more details. EN can be connected to
IN if not used.
Fixed voltage versions only—connecting an external capacitor to this pin bypasses noise generated by the
NR 4
internal bandgap, reducing output noise to very low levels.
Adjustable voltage version only—this is the input to the control loop error amplifier, and is used to set the
FB 4
output voltage of the device.
OUT 5 Output of the regulator. There are no output capacitor requirements for stability.
