5 / 24 page LT3070 5 3070p ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. COUT = 15μF (Note 9), VIN = VOUT + 0.3V (Note 5), VBIAS = 2.5V unless otherwise noted. PARAMETER CONDITIONS MIN TYP MAX UNITS VBIAS Ripple Rejection VBIAS = VOUT + 1.5VAVG, VRIPPLE =0.5VP-P , fRIPPLE = 120Hz, VIN – VOUT = 300mV, IOUT = 2.5A 60 72 dB VIN Ripple Rejection (Notes 3, 4, 5) VBIAS = 2.5V, VIN – VOUT = 300mV, IOUT = 2.5A, VRIPPLE = 50mVP-P, fRIPPLE = 120Hz 60 68 dB Reference Voltage Noise (REF/BYP Pin) CREF/BYP = 10nF, BW = 10Hz to 100kHz 10 μVRMS Output Voltage Noise VOUT = 1V, IOUT = 5A, CREF/BYP = 10nF, COUT = 15μF, BW = 10Hz to 100kHz 25 μVRMS 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 LT3070 regulators are tested and specified under pulse load conditions such that TJ ≅ TA. The LT3070E 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 LT3070I is guaranteed over the –40°C to 125°C operating junction temperature range. The LT3070MP is 100% tested and guaranteed over the –55°C to 125°C operating junction temperature range. Note 3: To maintain proper performance and regulation, the BIAS supply voltage must be higher than the IN supply voltage. For a given VOUT, the BIAS voltage must be in the range: (1.2 • VOUT + 935mV) ≤ VBIAS ≤ 3.6V. Note 4: Operating conditions are limited by maximum junction temperature. The regulated output voltage specification does not apply for all possible combinations of input voltage and output current. When operating at maximum output current, limit the input voltage range to: VIN < VOUT + 500mV. Note 5: The LT3070 incorporates safe operating area protection circuitry. Current limit decreases as the VIN-VOUT voltage increases. Current limit foldback starts at VIN – VOUT > 500mV. See the Typical Performance Characteristics for a graph of Current Limit vs VIN – VOUT voltage. The current limit foldback feature is independent of the thermal shutdown circuity. Note 6: Dropout voltage, VDO, is the minimum input to output voltage differential at a specified output current. In dropout, the output voltage equals VIN – VDO. Note 7: GND pin current is tested with VIN = VOUT(NOMINAL) + 300mV and a current source load. VIOC is a buffered output determined by the value of VOUT as programmed by the VO2-VO0 pins. VIOC’s output is independent of the margining function. Note 8: Reverse output current is tested with the IN pins grounded and the OUT + SENSE pins forced to the rated output voltage. This is measured as current into the OUT + SENSE pins. Note 9: Frequency Compensation: The LTC3070 must be frequency compensated at its OUT pins with a minimum COUT of 15μF configured as a cluster of (15 ×) 1μF ceramic capacitors or as a graduated cluster of 10μF/4.7μF/2.2μF ceramic capacitors of the same case size. Linear Technology only recommends X5R or X7R dielectric capacitors. |
