=> IC=IL-IO=1A-111mA =889mA. 12. Calculate the output voltage for LM314 regulator. The current IADJ is very small in the order of 100µA. (Assume VREF=1.25v)
A. 17.17v
B. 34.25v
C. 89.34v
D. 23.12v
Answer:A
=> IC=IL-IO=1A-111mA =889mA. 12. Calculate the output voltage for LM314 regulator. The current IADJ is very small in the order of 100µA. (Assume VREF=1.25v)
A. 17.17v B. 34.25v C. 89.34v D. 23.12v
Explanation: The output voltage, VO =VREF[1=(R2/R1)]+(IADJ×R2)=1.25Vin× [1+(3kΩ/240Ω)] +( 100µA×3kΩ )= 16.875 +0.3.
