APPLICATION NOTES

UNBALANCED LOADS

Unbalanced loads may be used on dual output models

with either side providing up to its rated current. Output

voltages, by design, will track each other in an unbal-

anced state within ±10% of one another.

OUTPUT NOISE

Output noise can be reduced to 30mVp-p, typically, by

adding a 10µF tantalum capacitor with an equivalent

series resistance (ESR) of less than 150mW at 10kHz

across each output.

TYPICAL PERFORMANCE CURVES

T = +25°C, Rated Input Voltage, Rated Output Current unless otherwise noted.
