Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the difference between the S-1315 Series C type and other types?

The S-1315 Series C type features an active 'H' ON/OFF logic, has the discharge shunt function unavailable, and includes the constant current source pull-down function.

Is an output capacitor required for the S-1315 Series?

An output capacitor is unnecessary for phase compensation. However, if used, a ceramic capacitor of 10 μF or less can be employed to stabilize operation.
