STK403-120 *Specifications and information herein are subject to change without notice. Note *1.1channel Operation. *2.All tests are measured using a constant-voltage supply unless otherwise specified. *3.The output noise voltage is peak value of an average-reading meter with a rms value scale(VTVM). A regulated AC supply(50Hz) should be used to eliminate the effects of AC primary line flicker noise. *4.Available time for load short-circuit and output noise voltage are measured using the specified transformer power supply. *5.Please keep the condition always most below Voltage ‘–Pre Vcc(#1pin)’. *6.In case of heat sink design, we request customer to design in the condition to have assumed market. *7.Please specify resistance value by satisfying ‘#13(Stand-By)pin’ Maximum Operating Current. This Circuit change operation mode to give above VBE(about 0.6v) voltage at ‘#13(Stand-By)pin’. Specified Transformer Power Supply (Equivalent to MG-250)
