ceramic substrate, and SMD construction,
provide genuine high reliability. Nominal input

1. Absolute maximum value for 30 seconds. Prolonged operation may damage the product.
2. Measured at full load with external input/output capacitors. Refer to application note.
3. A lower load condition can be used but higher levels of output ripple may be experienced, this condition may also cause the output
voltage to exceed its speci?cation transiently during power down when the input voltage also falls below its rated minimum.
All speci?cations typical at T A =25°C, Nominal input voltage and rated output current unless otherwise speci?ed.
