1A Switching voltage regulator series

780X replacement

3.3V OR 5.0V fixed voltage available

Price: $17.60 (Incl. GST)

 


Specifications

* The SW033/SW050 family is pin-compatible with the common 780X family of linear voltage regulators.
* They have integrated decoupling capacitors, so external capacitors are not generally necessary.

Performance:
* Up to 30V input range
* 83% typical efficiency, up to 87%
* <2% ripple
* 1A output (continuous)
* 1.25A peak output (1 min)
* 1.3V typical dropout voltage at full load
* Can be put in parallel


Please specify 3.3v (SW033) or 5.0v (SW050) when ordering.
