One-Time Programming Procedure Output Voltages
The three LDOs can be programmed and burned to any output voltage between 1.8 and 3.3V in steps of 0.1V. Cus-
tomers can burn the desired output voltages onsite using the austriamicrosystems programming board.
Furthermore, the AS1357 is available in pre-programmed versions with fixed output voltages (see Ordering Information
on page 9.)
