I just received from Digi-Key link https://www.digikey.com/scripts/DkSearch/dksus.dll?Detail?Ref=47431&Row=208451&Site=US
2.5V 250ma TO-92 3 pins and I only get 1 volt output from Regulator. I use 4AA batteries. Vin is 5.7v to pin3, ground pin2 and Vout pin1. I tried with 1k and 0.2K load and I still get 1v on Vout pin1. Also I used with and without Capacitors 2.2uf and 0.1uf. What is going on? On chip it says L4931; st 25; yo247. I bought from digikey 10 of these regulators and they are all the same. Please help
