All 4 pins

Pin	Signal	Direction	Function
1	VIN Supply	Supply	Unregulated positive supply. Allow voltage headroom for dropout and keep the return path short.
2	GND Return	Return	Supply and load return for the fixed-voltage regulator.
3	VOUT Output	Output	Regulated output. Fit the output capacitor close to the device.
TAB	GND Return	Return	Metal tab connected to GND internally. Include its net when laying out the footprint.

Signal assignments

Regulated supply

The input must exceed the selected output by the dropout headroom at the actual load. Check dissipation from input–output voltage difference times load current.

Nominal output1.2 V	1.2 V	Fixed output selected by the order code. Diodes / BCD AP2114 Rev. 2.2, Ordering Information
Input supply2.5–6.0 V	2.5–6.0 V	Recommended range. VIN must also provide headroom for the selected VOUT and load. Diodes / BCD AP2114 Rev. 2.2, Recommended Operating Conditions
Output current class1 A	1 A	Electrical test limits are version-specific. At large VIN − VOUT, SOT-223 thermal dissipation can become the limiting factor. Diodes / BCD AP2114 Rev. 2.2, Electrical Characteristics
