(1) The TL1963A-Q1 regulators are tested and specified under pulse load conditions such that TJ ≈ TA. The TL1963A-Q1 is fully tested at TA = 25°C. Performance at –40°C and 125°C is specified by design, characterization, and correlation with statistical process controls.
(2) Typical values represent the likely parametric nominal values determined at the time of characterization. Typical values depend on the application and configuration and may vary over time. Typical values are not ensured on production material.
(3) The TL1963A-Q1 (adjustable version) is tested and specified for these conditions with the ADJ pin connected to the OUT pin.
(4) For the TL1963A-Q1, TL1963A-Q1-1.5 and TL1963A-Q1-1.8, dropout voltages are limited by the minimum input voltage specification under some output voltage and load conditions.
(5) 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 input voltage, the output current range must be limited. When operating at maximum output current, the input voltage range must be limited.
(6) Dropout voltage is the minimum input to output voltage differential required to maintain regulation at a specified output current. In dropout, the output voltage is equal to: VIN – VDROPOUT.
(7) To satisfy requirements for minimum input voltage, the TL1963A-Q1 (adjustable version) is tested and specified for these conditions with an external resistor divider (two 4.12-kΩ resistors) for an output voltage of 2.4 V. The external resistor divider adds a 300-mA DC load on the output.
(8) GND pin current is tested with VIN = (VOUT(NOMINAL) + 1 V) and a current source load. The GND pin current decreases at higher input voltages.
(9) ADJ pin bias current flows into the ADJ pin.
(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.
