Note:
1. C_IN: A 1.0 µF capacitor (or larger) should be placed between V_IN to GND.
2. C_OUT: A 1.0 µF (or larger) capacitor is recommended between V_OUT and GND for stability and improving the regulator’s transient response. The
ESR (Effective Series Resistance.) of this capacitor has no effect on regulator stability, but low ESR capacitors improve high frequency transient
response. The value of this capacitor may be increased without limit, but values larger than 10uF tend to increase the settling time after a step
change in input voltage or output current. The part may oscillate without the capacitor. Any type of capacitor can be used, but not Aluminum
electrolytics when operating below -25 ^OC, The capacitance may be increased without limit.
