NOTE:

1. Measured from High Line to Low Line (Vo set to 3.3VDC).

2. Measured from Full Load to No Load (Vo set to 3.3VDC).

3. Output noise & ripple is measured with a 10µF tantalum & 1µF ceramic capacitor across the output.

4. It is recommended to put a 100µF capacitor with ESR<100mΩ across the input to reduce the input ripple voltage.

5. Suffix ‘N’ to model number for Negative Logic Remote On/Off Control.

6. Suffix ‘P’ to model number for Power Good function.

Typical at nominal line, full load & 25°C unless otherwise stated.
