When the output load is higher than the one supported by the device, the output current increases until the limit of typically 2 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, therefore the IC shuts down. As soon as the junction temperature falls again 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 )/RTHJ A 6.2 Output voltage setting for ADJ version In the adjustable version, the output voltage can be set from 0.8 V up to the input voltage minus the voltage drop across the pass transistor (dropout voltage), by connecting a resistor divider between the ADJ pin and the output, thus allowing remote voltage sensing. The resistor divider could be selected by the following equation: Equation 2 It is recommended to use resistors with values in the range of 10 kΩ to 50 kΩ. Lower values can also be suitable, but current consumption increases. DocID026319 Rev 2 9/32 Application information 6.3 LDL112 Reverse current protection The device avoids the reverse current to flow from output to input during any operating condition (with enable pin in high or low status).The reverse current protection acts in particular during fast turning on/off operations or when another power supply (with higher voltage than the input one) is connected to the output port. If a power supply with lower voltage than the LDO output voltage is connected to VOUT pin, LDO enters the current protection status, causing high power dissipation. In the application, the LDL112 reverse current protection acts in the following cases: 1. 2. 3. 10/32 Off-state, EN pin is at GND level, VOUT > [VIN + 100 mV]. In this case the device power pass element (MOSFET) is off, the bulk and gate are switched to VOUT and therefore all possible current paths from VOUT to VIN are interrupted. On-state, EN pin is at high level and VOUT > VOUT(nominal). In this condition, VOUT is higher than the nominal level, so the device op-amp works in open loop and the power element is off. VGS is zero, the bulk and gate are switched to VOUT (where VOUT > [VIN + 100 mV]) therefore all possible current paths from VOUT to VIN are interrupted. On-state, EN pin is at high level and VOUT< VOUT(nominal). In this condition VOUT is lower than the nominal level, so the op-amp works in open loop with the power MOSFET on. VGS is maximal so the power channel conducts with very low R DS(on). When VOUT > VIN the current can flow from VOUT to VIN until the condition VOUT > (VIN + 100 mV) is reached.
