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

What is the function of the 'D' suffix in the part number?

The 'D' suffix indicates that the regulator includes an internal N-channel auto-discharge resistor connected to the output, which rapidly pulls down the output voltage when the enable pin is deactivated.

How does the enable pin operate?

The regulator is turned on by driving the EN pin high and enters shutdown mode when pulled low. If always-on operation is desired, the EN pin should be tied directly to the IN pin.
