PIN		TYPE	DESCRIPTION
NO.	NAME	TYPE	DESCRIPTION
A1	OUT	Output	Regulated output pin. A 1-µF or greater capacitance is required from OUT to ground for stability. For best transient response, use a 2.2-µF or larger ceramic capacitor from OUT to ground. Place the output capacitor as close to OUT as possible.
A2	IN	Input	Input pin. A 0.75-µF or greater capacitance is required from IN to ground for stability. For good transient response, use a 2.2-µF or larger ceramic capacitor from IN to ground. Place the input capacitor as close to input of the device as possible.
B1	SENSE	Input	SENSE input. This pin is a feedback input to the regulator for SENSE connections. Connecting SENSE to the load helps eliminate voltage errors resulting from trace resistance between OUT and the load.
B2	EN	Input	Enable pin. Driving this pin to logic high enables the LDO. Driving this pin to logic low disables the LDO. If enable functionality is not required, this pin must be connected to IN or BIAS.
C1	GND	—	Ground pin. This pin must be connected to ground.
C2	BIAS	Input	BIAS pin. This pin enables the use of low-input voltage, low-output voltage (LILO) conditions. For best performance, use a 0.1-µF or larger ceramic capacitor from BIAS to ground. Place the bias capacitor as close to BIAS as possible.
