Typical Applications
*Required if the regulator is located more than 3″ from the power supply filter. **See (1) in the electrical characteristics table.
Figure 13. Fixed Output Regulator
VOUT = 5V + (5V/R1 + IQ) R2 5V/R1 > 3 IQ, load regulation (Lr) ≈ [(R1 + R2)/R1] (Lr of LM78L05)
Figure 14. Adjustable Output Regulator
IOUT = (VOUT/R1) + IQ >IQ = 1.5mA over line and load changes
Figure 15. Current Regulator
(1) Recommended minimum load capacitance of 0.01μF to limit high frequency noise.
