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 output discharge feature, which actively pulls the output voltage down when the device is disabled.

How is the Enable pin utilized?

The Enable pin controls the state of the regulator; driving it high activates the output, while pulling it low places the device into shutdown mode.
