FAQ
Does the LD29080PT33R support adjustable output voltages?
No, the PT suffix indicates a fixed 3.3V output version. Adjustable variants exist within the broader LD29080 family but require different ordering codes.
What is the maximum input voltage for this regulator?
The maximum input voltage is 13V. Exceeding this limit may damage the device.
