Fixed mode example * Recommended Ceramic Capacitors for Vin and Vout: 1uF B. Adjustable (ADJ) mode example The adjustable-version device requires external feedback divider resistors to set the output voltage. VOUT is set using the feedback divider resistors, R1 and R2 , according to the following equation: VOUT = VFB × (1 + R1 / R2 ) For this device, VFB = 0.85 V. To ignore the FB pin current error term in the VOUT equation, set the feedback divider current to 100x the FB pin current listed in the Electrical Characteristics table. This setting provides the maximum feedback divider series resistance, as shown in the following equation: R1 + R2 ≤ VOUT / (IFB × 100) For this device, IFB = 10 nA. 上海洺太电子科技有限公司 -8- SUNTEK MICRO LTD ABSOLUTE MAXIMUM RATINGS RECOMMENDED OPERATING CONDITIONS ELECTROSTATIC DISCHARGE 上海洺太电子科技有限公司 -9- SUNTEK MICRO LTD THERMAL DATA ELECTRICAL CHARACTERISTICS VIN = VOUT + 1.0 V, IOUT = 1 mA, CIN = COUT = 1.0 μF, typical values are at TJ = 25 °C; unless otherwise noted. 上海洺太电子科技有限公司 - 10 - SUNTEK MICRO LTD ELECTRICAL CHARACTERISTICS (continued) *This is SUL6001D8-33 measurement data.

Short-Circuit Protect and Current Limitation SUL6001 series LDOs can protect internal circuit under short-circuit condition on the output. When the load current increases above 1.55 A, the current limit and current foldback mechanism starts to restrict the ILIM value. If the load resistance decreases even more then the foldback, circuit starts limiting the current to 0.2 A when VOUT = 0. B. Over Temperature Protection and Auto Recover In order to prevent over thermal condition from damaging the device, SUL6001 series LDOs have internal thermal limiting functions designed to protect the device. It will rapidly shut off PMOS pass element during over temperature condition. C. Current Foldback The current limiting/ current foldback circuit plays an important role by controlling any excessive output current. Our SUL6001 series LDOs provide a current foldback circuit that can detect accurately when an over-current condition occurs. D. Very Fast Transient Response In addition to the main feedback loop, SUL6001 series LDOs contain a fast-transient loop that allows the LDO to respond faster to large-output transients. SUL6001 series LDOs that contain this loop are better able to minimize the effects of a load transient even the output capacitance is small. The recommended output capacitance value is 1μF. It’s small size greatly reduce the cost and save PCB area. E. Ultra High PSRR and Extreme Low Noise SUNTEK’s SUL6001 series high-performance LDO regulators feature remarkable power supply rejection ratio characteristics (up to 104 dB at 10 kHz) and extreme-low noise operation (as low as 6.3 µVRMS with A-wt) resulting in cleaner and stable output voltages. Our LDO is very suitable for ultra-sensitive loads like camera module and security monitor, especially in low light condition. 上海洺太电子科技有限公司 - 14 - SUNTEK MICRO LTD F. Start-Up at Full Load SUL6001 series LDOs can start-up at full load, make it very suitable for heavy load start up condition and severe system timing constraint. G. Auto Discharge Function SUL6001 series LDOs have an auto discharge function to quickly force the output voltage to zero. When the LDO is disabled, the auto discharge function quickly discharge the output capacitor, thereby reducing the output voltage to nearly zero. This function is very useful for quickly ON/OFF application. H. Low Quiescent Current SUL6001 series LDOs consume only 85μA (typical) while operating with no load condition. By reducing the quiescent current, your application can stay in standby/sleep mode much longer than leading low quiescent current LDOs in the market. I. Uuder Voltage Lock OUT (UVLO) SUL6001 has an undervoltage lockout (UVLO) function to make sure that whole circuit does nothing until the power supply voltage is high enough. When power supply voltage is high enough, reference circuit can generate right voltage ; logic function can generate correct control signals. This UVLO function can guarantee robust system performance. 上海洺太电子科技有限公司 - 15 - SUNTEK MICRO LTD TYPICAL CHARACTERISTICS VIN = VSET(1) + 1.0 V, IOUT = 1 mA, CIN = COUT = 1.0 μF, LCON=’H’, typical values are at TJ = 25 °C; unless otherwise noted.
