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

What is the logic level for the ON/OFF pin?

The 'B' in the part number indicates positive logic, where a High signal turns the regulator ON and a Low signal turns it OFF.

Can I use tantalum capacitors for this regulator?

Yes, but the equivalent series resistance (ESR) must be 2.0 Ω or less, and capacitance must be 0.1 μF or more.
