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

How does the ON/OFF pin function for the 'B' product type?

For the 'B' product type, the ON/OFF pin uses positive logic. Setting the pin to a high level turns the regulator ON, while setting it to a low level turns it OFF.

What are the recommended external capacitor values?

Both the input capacitor (CIN) and output capacitor (CL) should be 0.1 μF or more. Ceramic capacitors with an equivalent series resistance (ESR) of 2.0 Ω or less are recommended for stability.
