Data Sheet 7 Rev. 2.5, 2007-03-20 TLE 4476 Application Information Ι 5.7 - 42 V Q1 CΙ 470 nF 3.3 V C Q1 22 μF Bandgap Reference Q2 5V C Q2 22 μF e.g. from Ignition EN GND AES02564 Figure 3 Application Circuit Input, Output The input capacitor CI is necessary for compensating line influences. Using a resistor of approx. 1 Ω in series with CI, the LC circuit of input inductivity and input capacitance can be damped. To stabilize the regulation circuits of the stand-by and main regulator, output capacitors CQ1 and CQ2 are necessary. Stability is guaranteed at values CQ1 ≥ 10 μF (ESR ≤ 2 Ω) and CQ2 ≥ 10 μF (ESR ≤ 3 Ω) within the operating temperature range. Enable Using the enable feature the output 2 (5 V output) can be switched ON or OFF. The enable input can be connected directly to terminal 30 (battery line) or 15 (ignition line). It is also possible to control the output 2 via the microcontroller.
