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 sufce.
3. When the products used as the circuit like gure 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
OUT
, if the input voltage of the model's negative output is less than 4.85 V, a dummy load of not less than 5 mA needs to be added to the output.
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 specications measured at: Ta=25°C, humidity<75%, nominal input voltage and rated output load, unless otherwise specied.
