It is available in DFN8 (1.2 x 1.6 mm) package, allowing the maximum space saving. The device is stabilized with a ceramic capacitor on the output. The ultra-low drop voltage, low quiescent current and fast transient response, together with the internal soft-start circuit, make the LD56100 suitable for low power battery-operated applications. An enable logic control function puts the LD56100 in shutdown mode allowing a total current consumption lower than 0.1 µA. Short-circuit protection with current limit foldback and thermal protection are also included.

By increasing the start-up time up to 100 µs, without the need of any external soft-start capacitor, this feature is able to keep the regulator inrush current at start-up under control. 6.2 Output discharge function The LD56100 integrates a MOSFET connected between Vout and GND. This transistor is activated when the EN pin goes to low logic level and has the function to quickly discharge the output capacitor when the device is disabled by the user. The device is available with or without the auto-discharge feature. See Ordering information for more details. 6.3 Short-circuit and current limitation The LD56100 is protected against short-circuit on the output. When the load current increases above 1.6 A typical the device starts limiting it to the ILIM value. If the load resistance decreases even more then the foldback, circuit starts limiting the current to 0.4 A when VOUT = 0. When pulling LCON pin to ground, the ILIM and ISC values are reduced to 0.8 A and 0.18 A respectively. 6.4 Input and output capacitors The LD56100 requires external capacitors to assure the regulator control loop stability. Any good quality ceramic capacitor can be used but, the X5R and the X7R are suggested since they guarantee a very stable combination of capacitance and ESR overtemperature. Locating the input/output capacitors as closer as possible to the relative pins is recommended. The LD56100 requires an input capacitor with a minimum value of 1 μF. This capacitor must be located as close as possible to the input pin of the device and returned to a clean analog ground. The control loop is designed to be stable with any good quality output ceramic capacitor (such as X5R/X7R types) with a minimum value of 1 μF and equivalent series resistance in the [3 – 300 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. The suggested combination of 1 μF input and output capacitors offers a good compromise among the stability of the regulator, optimum transient response and total PCB area occupation.
