Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ
What is the purpose of the 'D' in the model number?
The 'D' indicates that the regulator includes an integrated auto-discharge function to pull the output voltage down when the device is disabled.
How does the enable pin operate?
Driving the EN pin high enables the regulator, while pulling it low puts the device into shutdown mode. It must not be left floating.
