Note:

1. When the products used as negative output and the input-voltage under (Vin-min+2V), C1 and C2 must be added in the circuit, and they should be placed as near as the

products' footprints. Others apply to the application-environment.

2. The capacitance of C1, C2, see external circuit table, can be increased if required, and tantalum or low ESR electrolytic capacitors may also suffice.

3. When the products used as the circuit like figure 4, an inductor named as LDM up to 10μH is recommended in the circuit to reduce the mutual interference.

4. For models ≤ 3.3 V

5. Cannot use in parallel for output and hot swap for input.

Note:

1. Max. capacitive load tested at input voltage range and full load.

2. All specifications measured at: Ta=25°C, humidity<75%, nominal input voltage and rated output load, unless otherwise specified.
