Single output
Dual output
On dual output models when one load is varied between
25% and 100% and other is fixed at 100%
For 3V3 & 5V output models / all other models.
Recovery within 2% in less than 2ms for a 25% load change
20 MHz bandwidth. Measured using 0.1 µF ceramic capacitor
Continuous, with auto recovery
See Models and Ratings table
Output is on if Remote On/Off (pin 3) is open
Output turns off if 2-4 mA is applied to Remote On/Off (pin 3). Referenced to -Vin.
No minimum load required
