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

How does the ON/OFF pin function for the S-1132B30-U5T1G?

The 'B' product type uses positive logic for the ON/OFF pin. Setting the pin to a high level turns the regulator ON, while setting it to a low level turns it OFF, significantly reducing current consumption.

What is the typical dropout voltage for this regulator?

The typical dropout voltage is 0.14 V when the output current is 100 mA and the set output voltage is between 2.5 V and 2.9 V.
