application of LD1117AS33TR
The LD1117A adjustable has a thermal stabilized 1.25 ± 0.012 V reference voltage between the OUT and ADJ pins. IADJ is 60 µA typ. (120 µA max.) and ΔIADJ is 1 µA typ. (5 µA max.). R1 is normally fixed to 120 Ω. From Figure 6 the following is obtained: VOUT = VREF + R2 (IADJ + IR1) = VREF + R2 (IADJ +VREF /R1) = VREF (1 + R2 / R1) + R2 x IADJ. In normal applications the R2 value is in the range of a few kΩ, so the R2 x IADJ product can not be considered in the VOUT calculation; the above expression then becomes: VOUT = VREF (1 + R2 / R1). In order to have a better load regulation it is important to realize a good Kelvin connection of R1 and R2 resistors. In particular, the R1 connection must be realized very close to the OUT and ADJ pins, while the R2 ground connection must be placed as near as possible to the negative load pin. Ripple rejection can be improved by introducing a 10 µF electrolytic capacitor placed in parallel to the R2 resistor (see Figure 8).
