## Questions & Answers

**Q: Will v-out stay stable w/ a changing v-in? for instance 14v in and set for 3 v out but over time input (battery) drops to 11v.**
A: I haven't monitored the Output Voltage vs. Input Voltage change, but I have noticed that the output tends to drift down as the output current increases.  I haven't seen it drop below the 2.5% allowed in the spec, though, and I have drawn as much as 2.3 Amps.

**Q: Is there any delay when supplying voltage till output is sent?**
A: Output voltage begins to ramp up within a few micro seconds (usec) of applying input voltage but it takes a few hundred usec to reach full output voltage.  The time to achieve full output depends on both the input and output voltage.  I was curious so I measured a few cases.  The times to reach full output voltage with a 470 Ohm load were:
10.0V in, 5.0V out: 288 usec
20.0V in, 5.0V out: 304 usec
20.0V in, 15.0V out: 570 usec
30.0V in, 15.0V out: 572 usec
30.0V in, 25.0V out: 662 usec
Cheers

**Q: I don't understand the limitations. Can it be used to bring 5V down to 3V?**
A: It absolutely can. I have used these to convert my 12V supply into both 5V and 3.3V

**Q: At 12 volts input and (say) 5 volts output, what is the quiescent (no-load) current on the 12 volt side?  Thanks!**
A: On my regulators the no load input current for 12V in 5V out is 7.8 mA with the output indicator LED installed.  With the LED, the no-load current depends strongly on output voltage rising to 23 mA  at 11V output.  With the LED removed the no load input current at 12 V in 5 V out is 6.0 mA.  Without the LED is independent of output voltage.
