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

Does the S-13R1G22-M5T1U3 support reverse current flow?

No, it includes built-in reverse current protection to prevent current from flowing back from the output to the input when the input voltage falls below the output level.

What is the minimum input voltage required for proper operation?

The minimum input voltage is 2.0 V, which allows for operation even when the battery voltage approaches the regulated output level.
