Internally Limited Lead Temperature (Soldering, 5 seconds) ................................................. 260 °C Operating Junction Temperature Range .................................... -40 °C to +125°C ELECTRICAL CHARACTERISTICS TJ=25 °C, VIN = VOUT + 1V, IL = 100μA, CL = 1μF, and VENABLE 2.4V. The denotes the specifications which apply over full temperature range -40 °C to +85°C, unless otherwise specified. PARAMETER MIN TYP MAX UNITS CONDITIONS Output Voltage Tolerance (VOUT) -1 +1 %VNOM -2 +2 Line Regulation 0.03 0.1 %/V 0.2 Load Regulation 0.1 0.2 % 0.5 IL = 1mA to 150mA Dropout Voltage (See Note 2) 30 50 mV IL = 100 μA (VIN - VO) 70 140 190 mV IL = 50mA 230 180 250 mV IL = 100mA 300 210 275 mV IL = 150mA 350 Quiescent Current (IGND) 0.05 1 μA VENABLE 0.4V 5 VENABLE 0.25V Ground Pin Current 70 125 μA IL = 100 μA (IGND) 150 350 600 IL = 50mA 800 750 1000 IL = 100mA 1500 1300 1900 IL = 150mA 2500 Ripple Rejection (PSRR) 70 dB Current Limit (ILIMIT) 360 500 mA VOUT = 0V Output Noise (eNO) 300 μVRMS IL = 10mA, CL = 1 μF, CIN= 1μF (10Hz - 100kHz.) 40 μVRMS IL = 10mA, CL = 10 μF, CBYP = 1 μF,CIN=1μF,(10Hz - 100kHz) Input Voltage Level Logic Low (VIL) 0.4 V OFF Input Voltage Level Logic High (VIL) 2.0 ON Input Supply Voltage ......................................... -20V to +20V Enable Input Voltage ......................................... -20V to +20V Input voltage ..................................................................................... +2.5V to 16V Operating Junction Temperature Range .................................... -40 °C to +125°C Enable Input Voltage .............................................................................. 0V to VIN SOT-23-5 ( JA) ................................................................................... See Note 1 RECOMMENDED OPERATING CONDITIONS Note 1: The maximum allowable power dissipation is a function of maximum operating junction temperature, TJ (max), the junction to ambient thermal resistance, and the ambient, JA, and the ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is given: PD (max) = (TJ (max) - TA)/ JA, exceeding the maximum allowable power limit will result in excessive die temperature; thus, the regulator will go into thermal shutdown. The JA of the SPX5205 is 220 °C/W mounted on a PC board. Note 2: Not applicable to output voltages of less than 2V. ABSOLUTE MAXIMUM RATINGS ENABLE Input Current 0.01 2 μA V IL 0.4V 3 20 V IH 2.0V Output Voltage Temperature Coefficient 57 ppm/ °C VIN = VOUT + 1V ≥ 2.5V 1.0 IL = 100uA to 1mA VIN = VOUT +1 to 16V and VEN ≤ 6V VIN = VEN =VOUT +1 ≤ 8V 0.2 %/V VIN = VEN =VOUT +1 to 16V Ta = 25°C to 85°C |
