1. Standard models have foldback mode current protection with a high peak load capability. This peak can be taken for 1 ms only.

2. For optional constant current versions, add suffix ‘B’ to model number (current limit range is 95-105% of max output current).
Not available on 3.3 V and 5 V models.

3. Ripple and noise measured using 0.1 µF ceramic and 22 µF electrolytic capacitor, 20 MHz bandwidth.

4. Part numbers in bold are stocking models. Others are build to order.

5. Other output voltages are available, contact factory for details.
