➀ Typical at TA = +25°C under nominal line voltage and full-load conditions, unless otherwise
noted. All models are tested and specified with an external 22µF output capacitor with a
200mΩ ESR and a 470µF input capacitor with 6Arms ripple-current rating and 20mΩ
ESR. See I/O Filtering and Noise Reduction for more details.
➁ Ripple/Noise (R/N) is tested/specified over a 20MHz bandwidth. Output noise may be further
reduced by installing additional external output caps. See I/O Filtering and Noise Reduction.
➂ These devices have no minimum-load requirements and will regulate under no-load conditions.
➃ Nominal line voltage, no-load/full-load conditions.
➄ These are only partial part numbers, refer to part number structure when ordering.
