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 integrated active output discharge circuit, allowing the output voltage to be rapidly pulled to ground when the device is disabled.

How does the enable pin operate on this device?

Driving the EN pin high enables the regulator output, while pulling the EN pin low places the regulator into shutdown mode and activates the output discharge function.
