I have an odd requirement:
* Vin 1.5VDC to 26VDC
* Vout anything from 1.0 to 5 VDC; need not be regulated below 5 VDC, but I need to to start at 1.5 VDC in, and get 1.0 VDC Out
* 40 mA
* prefer TO-92
The part that came closest is the LP2950-3.3 and LP2950-5.0; both have output that starts at 1.7 VDC, but output is only 0.6 VDC at the voltage.
At 1.8 VDC in, I get 1.2VDC out; almost good enough, but I need to start a bit lower.
LM9036Q had no output until 4 VDC Vin
Any other parts I might try?
