9.2.2.3.1 Support Component Selections RPGOOD and C(IN)

The RPGOOD serves as pull-up for the open-drain output. The current sink by this pin must not exceed 10mA (see the Absolute Maximum Ratings table). TI recommends typical resistance value in the range from 10kΩ to 100kΩ for RPGOOD. Figure 9-5 and Figure 9-7 illustrate the power up and power down performance of the system respectively. The CIN is a local bypass capacitor to suppress noise at the input. TI recommends a minimum of 0.1µF for C(IN).
