4 / 20 page LT3024 4 3024fa ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. (Note 2) PARAMETER CONDITIONS MIN TYP MAX UNITS Current Limit Output 2, VIN = 7V, VOUT = 0V VIN = 2.3V, ΔVOUT = –0.1V l 110 200 mA mA Output 1, VIN = 7V, VOUT = 0V VIN = 2.3V, ΔVOUT = –0.1V l 520 700 mA mA Input Reverse Leakage Current VIN = –20V, VOUT = 0V l 1mA Reverse Output Current (Notes 3,10) VOUT = 1.22V, VIN < 1.22V 5 10 μA Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: The LT3024 is tested and specified under pulse load conditions such that TJ ≅ TA. The LT3024E is 100% tested at TA = 25°C. Performance at – 40°C and 125°C is assured by design, characterization and correlation with statistical process controls. The LT3024I is guaranteed over the full –40°C to 125°C operating junction temperature range. Note 3: The LT3024 is tested and specified for these conditions with the ADJ1/ADJ2 pin connected to the corresponding OUT1/OUT2 pin. Note 4: Operating conditions are limited by maximum junction temperature. The regulated output voltage specification will not apply for all possible combinations of input voltage and output current. When operating at maximum input voltage, the output current range must be limited. When operating at maximum output current, the input voltage range must be limited. Note 5: To satisfy requirements for minimum input voltage, the LT3024 is tested and specified for these conditions with an external resistor divider (two 250k resistors) for an output voltage of 2.44V. The external resistor divider will add a 5μA DC load on the output. Note 6: Dropout voltage is the minimum input to output voltage differential needed to maintain regulation at a specified output current. In dropout, the output voltage will be equal to: VIN – VDROPOUT. Note 7: GND pin current is tested with VIN = 2.44V and a current source load. This means the device is tested while operating in its dropout region or at the minimum input voltage specification. This is the worst-case GND pin current. The GND pin current will decrease slightly at higher input voltages. Total GND pin current is equal to the sum of GND pin currents from Output 1 and Output 2. Note 8: ADJ1 and ADJ2 pin bias current flows into the pin. Note 9: SHDN1 and SHDN2 pin current flows into the pin. Note 10: Reverse output current is tested with the IN pin grounded and the OUT pin forced to the rated output voltage. This current flows into the OUT pin and out the GND pin. Note 11: For the LT3024 dropout voltage will be limited by the minimum input voltage specification under some output voltage/load conditions. See the curve of Minimum Input Voltage in the Typical Performance Characteristics. |
