➀Typical at TA = +25°C under nominal line voltage and full-load conditions, unless otherwise

noted. All models are tested and specified with external output capacitors (1µF ceramic in	P A R T N U M B E R S T R U C T U R E
parallel with 10µF tantalum).

➁ Contact DATEL for fixed output voltages (such as 2, 6.5, –5.2V) or higher output currents

(such as 12V @ 12.5A) other than those listed.

➂ Ripple/Noise (R/N) is tested/specified over a 20MHz bandwidth. Output noise may be further

reduced with the installation of additional external output filtering. See I/O Filtering, Input
