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

What is the function of the pull-down resistor in the S-13A1Cxx series?

The pull-down resistor connects the ON/OFF pin to ground when the pin is in a high-impedance state, ensuring the regulator remains off.

Can the output voltage be adjusted externally?

No, the S-13A1C22-A6T1U3 has an internally set output voltage of 2.2 V and does not support external adjustment.
