One-Time Programming Procedure Output Voltages

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

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

Furthermore, the AS1351 is available in pre-programmed versions with fixed output voltages (see Ordering Information

on page 9.)
