LM2936Q Ultra-Low Quiescent Current LDO Voltage Regulator General Description Features The LM2936Q ultra-low quiescent current regulator features low dropout voltage and low current in the standby mode. With less than 15 μA quiescent current at a 100 μA load, the LM2936Q is ideally suited for automotive and other battery operated systems. The LM2936Q retains all of the features that are common to low dropout regulators including a low dropout PNP pass device, short circuit protection, reverse battery protection, and thermal shutdown. The LM2936Q has a 40V maximum operating voltage limit, a −40°C to +125°C operating temperature range, and ±3% output voltage tolerance over the entire output current, input voltage, and temperature range. The LM2936Q is available in a SO-8 package, SOT-223 surface mount package and TO-252 surface mount package. ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ AEC-Q100 Grade 1 Qualified (-40°C to 125°C) Ultra low quiescent current (IQ ≤ 15 μA for IO = 100 μA) Fixed 3.0V, 3.3V or 5.0V with 50 mA output ±2% Initial output tolerance ±3% Output tolerance over line, load, and temperature Dropout voltage typically 200 mV @ IO = 50 mA Reverse battery protection −50V reverse transient protection Internal short circuit current limit Internal thermal shutdown protection 40V operating voltage limit 60V operating voltage limit for LM2936HV Shutdown pin available with the LM2936BM package Typical Application 30131901 * Required if regulator is located more than 2″ from power supply filter capacitor. ** Required for stability.

DC and AC electrical specifications do not apply when operating the device beyond its specified operating ratings. Note 2: Human body model, 100 pF discharge through a 1.5 kΩ 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 LM2936Q will go into thermal shutdown. Note 4: Typicals are at 25°C (unless otherwise specified) and represent the most likely parametric norm. Note 5: Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis. Note 6: To ensure constant junction temperature, pulse testing is used. www.ti.com 6 LM2936Q Typical Performance Characteristics Dropout Voltage Dropout Voltage 30131908 30131909 Quiescent Current Quiescent Current 30131910 30131911 Quiescent Current Quiescent Current 30131912 30131913 7 www.ti.com LM2936Q Quiescent Current LM2936Q–3.0 COUT ESR 30131914 30131929 LM2936Q–5.0 COUT ESR LM2936Q–3.3 COUT ESR 30131915 30131930 Peak Output Current Peak Output Current 30131916 www.ti.com 30131917 8 LM2936Q LM2936Q–5.0 Current Limit LM2936Q–5.0 Line Transient Response 30131918 30131919 LM2936Q–5.0 Output at Voltage Extremes LM2936Q–5.0 Ripple Rejection 30131921 30131920 LM2936Q–5.0 Load Transient Response LM2936Q–5.0 Low Voltage Behavior 30131923 30131922 9 www.ti.com LM2936Q LM2936Q–5.0 Output Impedance 30131924 www.ti.com 10 Unlike other PNP low dropout regulators, the LM2936Q remains fully operational to 40V. Owing to power dissipation characteristics of the available packages, 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. For the SO-8 and TO-252 surface mount packages the θJA rating can be improved by using the copper mounting pads on the printed circuit board as a thermal conductive path to extract heat from the package. On the SO-8 package the four ground pins are thermally connected to the backside of the die. Adding approximately 0.04 square inches of 2 oz. copper pad area to these four pins will improve the θJA rating to approximately 110°C/W. If this extra pad are is placed directly beneath the package there should not be any impact on board density. On the TO-252 package the ground tab is thermally connected to the backside of the die. Adding 1 square inch of 2 oz. Shutdown Pin The LM2936QHBMA–5.0 has a pin for shutting down the regulator output. Applying a Logic Level High (>2.0V) to the Shutdown pin will cause the output to turn off. Leaving the Shutdown pin open, connecting it to Ground, or applying a Logic Level Low (<0.6V) will allow the regulator output to turn on. 11 www.ti.com LM2936Q copper pad area directly under the ground tab will improve the θJA rating to approximately 50°C/W. While the LM2936Q has an internally set thermal shutdown point of typically 160°C, this is intended as a safety feature only. Continuous operation near the thermal shutdown temperature should be avoided as it may have a negative affect on the life of the device. While the LM2936Q maintains regulation to 60V, it will not withstand a short circuit above 40V because of safe operating area limitations in the internal PNP pass device. Above 60V the LM2936EP 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 60V.
