TK11818 ELECTRICAL CHARACTERISTICS
Test Conditions: V
TK11819 ELECTRICAL CHARACTERISTICS
Test Conditions: V
Note 1: Power dissipation is 400 mW when mounted. Derate at 3.2 mW/ C for operation above 25 C. Power dissipation is 200 mW in free air. Derate
Note 2: When operating below 25 C, the output capacitor degradation may increase output ripple noise.
Note 3: V
Note 4: Load Regulation = ( V
Note 5: Specifications are based upon a Toko 395GN-0091IB inductor. The use of other inductors may degrade performance.
Note 6: See Output Voltage Selection Table for connections to obtain desired output voltage.
