PRODUCTION DATA
This is assuming the table for the standard capacitor values is put back in as Table 6-1.
Using Table 7-2, R1 is selected to be 4.12 kΩ for VOUT = 1.5 V and R2 is 4.75 kΩ. Using Table 6-1, CSS is 1000 pF for a 1-ms typical start-up time. For optimal performance, 5-V rail for a Bias supply is used. And R3 of 100 kΩ is selected as the PG bus is used by other devices with additional 100-kΩ pullup resistors.
A CIN of 10 µF is used for better transient performance on the input supply, a CBIAS of 1 µF is used to verify that the Bias supply is solid, and a COUT of 1 µF is used to provide some local capacitance on the output.
