Ultra-low quiescent current of 5 µA makes it suitable for applications permanently connected to power supply/battery. This feature is also useful when electronic modules remain permanently turned on. The ST732 embeds protection functions, such as: current limit, short-circuit and thermal shutdown. The extended input voltage range, very low drop voltage and low quiescent current features make it suitable also for low power after-market automotive and consumer applications.

These capacitors must be selected to meet the requirements of minimum capacitance and equivalent series resistance defined in the following chapters. Input and output capacitors should be located as close as possible to the relevant pins. Input capacitor An input capacitor, whose minimum value is 0.1 μF, must be placed as close as possible to the input in of the device and returned to a clean analog ground. A good quality, low-ESR ceramic capacitor is suggested. It helps to ensure stability of the control loop, reduces the effects of inductive sources and improves ripple rejection. Values, which are higher than 0.1 µF, are suggested in case of fast load transients in the application. There is no maximum limit to the output capacitance. Output capacitor The ST732 requires a capacitor connected on its output, to keep the control loop stable and reduce the risk of ringing and oscillations. The control loop is designed to be stable with any good quality ceramic capacitor (such as X5R/X7R types) with a minimum value of 0.47 µF and equivalent series resistance in the [5 – 500 mΩ] range. It is important to highlight that the output capacitor must maintain its capacitance and ESR in the stable region over the full operating temperature, load and input voltage ranges, to assure stability. Therefore, capacitance and ESR variations must be taken into account in the design phase to ensure the device works in the expected stability region. There is no maximum limit to the output capacitance, provided that the above conditions are satisfied. 6.2 Power dissipation A proper PCB design is recommended, to ensure that the device internal junction temperature is kept below 125 °C, in all operating conditions. The thermal energy, generated by the device, flows from the die surface to the PCB copper area through the package leads. The PCB copper area acts as a heat sink. The footprint copper pads should be as wider as possible to spread and dissipate heat to the surrounding environment. Thermal micro-vias to the inner or backside copper layers improve the overall thermal performance of the device. The power dissipation of the LDO depends on the input voltage, output voltage and output current, and is given by: The junction temperature of the device is: PD = VIN − VOUT IOUT (1) T J_MAX = TA + RtℎJA × PD (2) where: TJ_MAX is the maximum junction of the die, 125 °C; TA is the ambient temperature; RthJA is the thermal resistance junction-to-ambient. With the above equation it is possible to calculate the allowable maximum power dissipation, therefore the maximum load current for a certain voltage drop. Appropriate de-rating of the operating condition can be applied accordingly. 6.3 Protection features Current limit Due to the wide input voltage range, high power dissipation could occur in case of damaged/shorted load. For this reason the ST732 embeds an SOA protection-current limit circuit, which acts in case of overload or short-circuit on the output, clamping the load current to a safe value. The current limit value on purpose depends on the voltage drop (VIN - VOUT), so that the maximum dissipated power is always kept under control. The non-constant current limit characteristic shown in Figure 15. Current limit vs. temperature should be taken into account to calculate the maximum load current the device can supply for a certain dropout voltage. Normal operation is restored if the overload disappears, but prolonged operation in current limit may lead to high power dissipation inside the LDO and subsequently to thermal shutdown. DS12561 - Rev 3 page 7/21 ST732 Protection features Thermal protection An internal thermal feedback loop disables the output voltage if the die temperature reaches approximately 160 °C. This feature protects the device from excessive temperature that could lead to permanent damage to the LDO. Once the thermal protection is triggered and the device is shut down, normal operation is automatically recovered if the die temperature falls below 140 °C (thermal protection hysteresis of 20 °C typically). Continuous operation above the maximum ratings may lead to permanent damage to the device. In case of operations with strongly inductive loads, undershoots on the output may happen. If those negative spikes overcome the absolute maximum ratings of the device, permanent damage may occur. A Schottky diode connected in parallel to the output port reduces the risk of damages in such operating cases.
