VI KA317 / LM317 VO
VADJ Input Ci
0.1 μF IADJ
R2 adj R1
240 Ω Output Co
1 μF VO = 1.25 V (1 + R2 / R1) + IADJR2 Figure 7. Typical Application
Note:
3. CI is required when the regulator is located an appreciable distance from power supply filter. CO is not needed for
stability; however, it does improve transient response. Since IADJ is controlled to less than 100 μA, the error
associated with this term is negligible in most applications. © 2002 Fairchild Semiconductor Corporation
