For heatsink option, add suffi x “H” to model number (i.e. MB5024S-03RU-H) Remote On/Off
Notes:
1. Start up time is measured at nominal input and with a constant resistive load. Applying a signal to pin 3 will turn the unit ON/OFF. If the pin is left open, the unit operates. If
2. Load regulation is specifi ed for a load change of minimum load to full load. grounded, the unit will shut off. The specifi cations for the ON/OFF function are:
3. When measuring output ripple, it is recommended that an external 1 µF capacitor and 10 µF capacitor be Parameter Min Typ Max Units
connected in parallel from the +VOUT to the -VOUT pins. Supply On 3.5 12.0 VDC
4. Transient recovery is measured to within a 1% error band for a load step change of 25%. Supply Off 0.0 1.2 VDC
5. Short circuit protection is provided by a “hiccup mode” circuit.
6. Operation at no-load will not damage the unit. Standby Input Current 2.5 mA
7. It is recommended that a fuse be used on the input of a power supply for protection. See the Model Selec- Control Common Referenced to Negative Input (pin 2)
tion table above for the correct rating. Control Input Current (ON) 0.5 mA
Control Input Current (OFF) -0.5 mA
