Hello
I want to produce a 5V / 1A for pic16f, I have a transformer 230 / 5V, diode bridge and filter capacitor, in the regulator input, I find the voltage 4.18V with isis I tried with the regulator vin 2.2V / 10V but I did not get a 5V voltage , i get 3.53V is there a solution for 5v .thank you
 

i used the transformer from WURTH ELEKTRONIK ( Transformateur d'isolation with 3 W,vin 85V à 265V,vout 5V) , standard power diodes 1N4007, capacitor2200uF, regulator
from TEXAS INSTRUMENTS LM2940IMP-5.0/NOPB Régulateur LDO , 0V à 26V, 500mV Dropout, 5Vout, 1Aout, SOT-223-3
 

Hi,

5V x 1A give 5W, but your transformer is only 3W.
