TK11819 ELECTRICAL CHARACTERISTICS
Test Conditions: V
IN = 5 V, TA = 25 °C (Notes 3 & 5), unless otherwise specified.
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
at 1.6 mW/°C for operation above 25 °C.
Note 2: When operating below 25 °C, the output capacitor degradation may increase output ripple noise.
Note 3: V
IN = 5.0 V, No load.
Note 4: Load Regulation = (V
OUT / VOUT) x 100 %, where VOUT = VOUT (no load) - VOUT (IOUT = 1.0 mA)
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.
