    Small size allows it to be easily fitter in my proto systems. Reasonable well requlated with load. I measured 70mV output drop when moving to no load to 550mA load. The test was made using a rechargeable 9V battery with 5V output setting. There was no noticeable temperature rise in the requlator when ... Read more

(frequency is fixed to around 1MHz for this device) According to datasheet peak efficiency (around 88%) seems to be at 1 to 2A output. Each terminal has two holes for wires. In-... Read more
