2. Start delay function
The SS pin has the internally-connected 10μA (typ) constant-current supply. When the voltage of SS pin exceeds
the threshold voltage, the regulator starts operation. As the threshold is 0.62V(typ), the start delay time can be
calculated as follows:
ex. For setting at 1μF
Td =
C×V

=
1μ × 0.4
