➀ Typical at TA = +25°C under nominal line voltage and full-load conditions, unless otherwise noted.
➁ Ripple/Noise (R/N) is tested/speciifed over a 20MHz bandwidth. All models are specified with two
external 0.47µF multi-layer ceramic capacitors installed across their output pins.
➂ Load regulation is specified over 10%-100% load conditions. 1.5-5V models are stable and
regulate under no-load conditions. 12/15V models have minimum loading requirements.
See Performance/Functional Specifications.
➃ Nominal line voltage, no-load/full-load conditions.
