VOUT(S)=Specified output voltage VOUT(E)=Effective output voltage, i.e., the output voltage when fixing IOUT(=10 mA) and inputting VOUT(S)+2.0V. 2. Output current at which output voltage becomes 95% of VOUT(E) after gradually increasing output current. 3. Vdrop=VIN1-(VOUT(E)×0.98), where VIN1 is the Input voltage at which output voltage becomes 98% of VOUT(E) after gradually decreasing input voltage. 4. Temperature change ratio for the output voltage [mV/°C] is calculated using the following equation. ΔVOUT ΔVOUT [mV / ℃] = VOUT (S)[ V ] × [ppm / ℃] ÷ 1000 ΔTA ΔTA • VOUT UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 4 of 6 QW-R502-495.b LR1012 Preliminary CMOS IC TERMS CL (Output capacitors) Cause the UTC LR1012L series can provide stable operation without CL.So the CL are used only to improve transient response characteristics.And when CL is used, a low ESR (Equivalent Series Resistance) capacitor like ceramic capacitor can also be used. CL can hence be removed in applications when transient response can be negligible. VOUT (Output voltage) Unless the under conditions change, the accuracy of the output voltage is ±2.0% guaranteed under the specified conditions for input voltage, which differs depending upon the product items, output current, and temperature. ΔVOUT1, ΔVOUT2 (Line regulations 1 and 2) After a change in the input voltage with the output current remained unchanged, these values show how much the output voltage changes. ΔVOUT3 (Load regulation) After a change in the output current with the input voltage remained unchanged, these values show how much the output voltage changes. Dropout voltage (Vdrop) When output voltage falls to 98% of VOUT (E) by gradually decreasing the input voltage (VIN), this value shows the difference between the input voltage (VIN1) and the output voltage.
