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

How does the reverse current protection function?

The reverse current protection circuit prohibits current flow from the VOUT pin to the VIN pin when the output voltage is higher than the input voltage, preventing damage from external power sources connected to the output.

What is the effect of leaving the CE pin open on the C-type version?

For the C-type version, which includes an internal pull-down resistor, leaving the CE pin open places the IC in the stand-by state, effectively turning off the circuitry.

What type of output capacitor is recommended?

The datasheet specifies the use of low ESR ceramic capacitors for phase compensation, with specific values depending on the nominal output voltage to ensure stability.
