NCV4275A

5.0 V, 3.3 V 450 mA Low-Dropout Voltage Regulator with Reset

ON Semiconductor 

NCV4275A

EMC−Characteristics: Conducted Susceptibility

All EMC−Characteristics are based on limited samples

and no part of production test according to 47A/658/CD

IEC62132−4 (direct Power Injection).

Test Conditions

Supply Voltage Vin = 12 V

Temperature TA = 23°C ±5°C

Load

RL = 100 W

Direct Power Injection

33 dBm (Note 1) forward power CW for global pin (Note 2)

17 dBm (Note 1) forward power CW for local pin (Note 3)

Acceptance Criteria

Amplitude Dev. max 4% of Output Voltage

Reset outputs remain in correct state ±1 V

1. dBm means dB mili−Watts, P(dBm) = 10 log

(P(mW)).

2. A global pin carries a signal or power which

enters or leaves the application board.

3. A local pin carries a signal or power which does

not leave the application board. It remains on the

application board as a signal between two

components.
