One-Time Programming Procedure Output Voltages

The four LDOs can be programmed and burned to any output voltage between 1.8V and 3.3V in steps of 0.1V. Cus-

tomers can burn the desired output voltages onsite using the austriamicrosystems programming board.

Furthermore, the AS1352 is available in pre-programmed versions with fixed output voltages (see Ordering Information

on page 9).
