Electrical specifications do not apply when operating the device outside of its operating ratings. The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(max) , the junction-to-ambient thermal resistance, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: PD(max) = (TJ(max) – TA) ÷ θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. ◈ Guaranteed Operating Conditions ( Ta = 25℃ ) Parameter Supply Input Voltage Enable Input Voltage Output Current Symbol VIN VCTL IOUT Limits Vo+0.5~20 0~ VIN 0~ 1.0 Unit V V A KSD-I0T009-002 Jan. 2011 REV. 02 3 S52Dxxx ◈ Electrical characteristics ( VIN=VOUT+1.0V, CIN = 0.33uF, COUT = 47 uF, IOUT = 5mA, TJ=25℃ ; unless noted ) NO Characteristics S52D00x S52D18x 1 Output Voltage S52D25x S52D33x S52D50x 2 3 4 5 6 7 8 9 10 11 12 Line Regulation Load Regulation Quiescent Current Ripple Rejection Dropout Voltage Current Limit Output Noise Voltage Output On state for VCTL Output OFF state for VCTL Output On state for ICTL Output OFF state for ICTL VLINE VLOAD IQC R·R VDROP ILIMIT VNO VCTL(ON) VCTL(OFF) ICTL(ON) ICTL(OFF) VCTL=2.0V VCTL=0.8V VIN=VOUT+1V to 12V, IOUT=5mA VIN=VOUT+1V, IOUT=5mA to 1A VIN=VOUT+1V to 20V, IOUT=0mA IOUT=50mA, f=120Hz IOUT=1.0A VIN=VOUT+1V VIN=VOUT+1V, IOUT=50mA, 10Hz ≤ f ≤ 100kHz - Symbol Condition MIN. 1.215 1.764 Specification TYP. 1.240 1.800 2.500 3.300 5.000 0.05 0.1 2.0 65.0 1300 100 MAX. 1.265 1.836 2.550 3.366 5.100 0.5 1.0 5.0 0.5 0.8 20 0.1 H : Enable L : Disable Unit V V V V V % % mA dB V mA uVrms V V uA uA VOUT Variation from nominal VOUT 2.450 3.234 4.900 53.0 1100 2.0 - Typical Application VCTL S52Dxxx VIN CIN CO RL + VOUT – 1) CIN should be required if regulators are located far from power supply filter 2) CO improves output stability and transient response ( CO ≥ 47uF ) KSD-I0T009-002 Jan. 2011 REV. 02 4 S52Dxxx Fig1.
