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

What is the typical dropout voltage for the S-1206B31?

The typical dropout voltage is 150 mV at an output current of 100 mA.

Does the S-1206B31 include thermal protection?

No, the built-in overcurrent protection circuit does not function as thermal protection; attention must be paid to power dissipation under short-circuit conditions.
