    hello,
    
 
    I have constructed a circuit based on adp1708 and am not getting 1V output.
    
 
    i had used R2=10k ohms and R1=2500 ohms for constructing the circuit.
    
 
    will use of ADR 510 solve this problem I need exact 1 V output

      Your component values seem ok there.  What is the 1V output for - is it a precision voltage reference or is it to power another device?
      
 
      If its a voltage reference, the ADR510 would be a good choice.  If you are looking to power another circuit, have you considered using ADP1707ARDZ-1.0-R7?  This is a fixed 1 Volt version of the ADP1708 and is pin compatible if R1 is removed and R2 replaced with a 10nF capacitor in the same package size.
