DC and AC electrical specifications do not apply when operating the device beyond its specified operating ratings. Note 2: Human body model, 100pF discharge through a 1.5kΩ resistor. Note 3: The maximum power dissipation is a function of TJmax, θJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJmax − TA)/θJA. If this dissipation is exceeded, the die temperature will rise above 150°C and the LM9036 will go into thermal shutdown. Note 4: Typicals are at 25°C (unless otherwise specified) and represent the most likely parametric norm. Note 5: Tested limits are guaranteed to National's AOQL (Average Outgoing Quality Level) and 100% tested. Note 6: To ensure constant junction temperature, pulse testing is used. Note 7: Worst case (Free Air) per EIA / JESD51-3. Note 8: Typical θJA with 1 square inch of 2oz copper pad area directly under the ground tab. www.national.com 4

Unlike other PNP low dropout regulators, the LM9036 re- mains fully operational to 40V. Owing to power dissipation characteristics of the package, full output current cannot be guaranteed for all combinations of ambient temperature and input voltage. The junction to ambient thermal resistance θJA rating has two distinct components: the junction to case thermal resistance rating θJC; and the case to ambient thermal resistance rating θCA. The relationship is defined as: θJA = θJC + θCA. On the TO-252 package the ground tab is thermally connect- ed to the backside of the die. Adding 1 square inch of 2 oz. copper pad area directly under the ground tab will improve the θJA rating to approximately 50°C/W. While the LM9036 has an internally set thermal shutdown point of typically 150°C, this is intended as a safety feature only. Continuous operation near the thermal shutdown tem- perature should be avoided as it may have a negative affect on the life of the device. Using the θJA for a LM9036DT mounted on a circuit board as defined at (Note 8), and using the formula for maximum al- lowable dissipation given in (Note 3) for an ambient temper- ature (TA) of +85°C, we find that PDMAX = 1.3W. Including the small contribution of the quiescent current IQ to the total power dissipation, the maximum input voltage (while still delivering 50mA output current) is 29.5V. The LM9036DT will go into thermal shutdown when attempting to deliver the full output current of 50mA, with an ambient temperature of +85°C, and the input voltage is greater than 29.5V. Similarly, with an am- bient temperature of 25°C the P DMAX = 2.5W, and the LM9036DT can deliver the full output current of 50mA with an input voltage of up to 40V. While the LM9036 maintains regulation to 55V, it will not with- stand a short circuit above 40V because of safe operating area limitations in the internal PNP pass device. Above 55V the LM9036 will break down with catastrophic effects on the regulator and possibly the load as well. Do not use this device in a design where the input operating voltage may exceed 40V, or where transients are likely to exceed 55V. www.national.com 6
