EQUIVALENT SERIES RESISTANCE (ESR) VS. OUTPUT CURRENT

Ceramic type output capacitor is recommended for this series; however, the other output capacitors with low

ESR also can be used. As for reference, the below graphs show the relationship between output current (IOUT)

and equivalent series resistance (ESR). The noise level of the output current (IOUT) was measured by the test

circuit and is lower than the specified value.

Measurement Conditions

・

Input Voltage: VOUT + 1 V to 24 V

・

Noise Frequency Range: 10 Hz to 1 MHz

・

Ambient Temperature: −40

°C to 125°C

・

Shaded Area: Noise level is lower than the specified value

・

Capacitor: C1 = Ceramic 0.47 µF, C2 = Ceramic 10 µF
