PRODUCTION DATA
The device is designed to be stable for all available types and values of output capacitors greater than or equal to 2.2 μF. The device is also stable with multiple capacitors in parallel, which can be of any type or value.
The capacitance required on the IN and BIAS pins strongly depends on the input supply source impedance. To counteract any inductance in the input, the minimum recommended capacitor for VIN and VBIAS is 1 μF. If VIN and VBIAS are connected to the same supply, the recommended minimum capacitor for VBIAS is 4.7 μF. Use good-quality, low-ESR capacitors on the input; ceramic X5R and X7R capacitors are preferred. Place these capacitors as close the pins as possible for optimum performance.
