When the output load is higher than the one supported by the device, the output current increases until the limit of typically 1.8 A is reached, at this point the current is kept constant even when the load impedance is zero. Thermal protection acts when the junction temperature reaches 165 °C typical. At this point the output of the IC shuts down. As soon as the junction temperature falls below the thermal hysteresis value the device starts working again. In order to calculate the maximum power that the device can dissipate, keeping the junction temperature below the TOP, the following formula is used: Equation 1 PDMAX = (125 - TAMB)/RTHJA 6.2 Output voltage setting for ADJ version In the adjustable version, the output voltage can be set from 0.5 V up to 4 V, by connecting a resistor divider between the ADJ pin and the output, thus allowing remote voltage sensing. The resistor divider should be selected using the following equation: Equation 2 VOUT = VADJ (1 + R1 / R2), with VADJ = 0.5 V (typ.) The resistors to be used, should have values in the range from 10 kΩ to 100 kΩ. Lower values can also be suitable, but they increase current consumption. 6.3 Bias pin voltage requirements The bias input is designed for low drop applications. The bias pin must be at least 2.7 V, and at least 1.5 V higher than the output, to ensure proper biasing to the N-channel power pass transistor. If VIN supply voltage meets these requirements, the bias pin can be tied to VIN. 6.4 External capacitors requirements The regulator is designed to be stable with ultra low ESR ceramic capacitors on the input and the output. The suggested minimum value of the input, bias and output capacitors is 1 μF. The input capacitor must be connected as closer as possible to the VIN terminal. The output capacitor must also be connected as closer as possible to the output pin.
