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

How does the B-type designation affect the CE pin configuration?

The B-type indicates High Active logic with no internal pull-down resistor. The CE pin must be actively driven by VIN or VSS to prevent undefined states.

What is the minimum output capacitor requirement for this voltage setting?

For the 3.1V output setting, a minimum output capacitance of 1.0µF is required to ensure stability.
