See Figure 10 for typical load regulation performance for loads less than 10 mA. 3 Dropout voltage is defined as the input-to-output voltage differential when the input voltage is set to the nominal output voltage. This applies only for output voltages above 2.5 V. 4 Start-up time is defined as the time between the rising edge of EN to OUT being at 95% of its nominal value. 5 Current limit threshold is defined as the current at which the output voltage drops to 90% of the specified typical value. For example, the current limit for a 1.0 V output voltage is defined as the current that causes the output voltage to drop to 90% of 1.0 V, or 0.9 V. Rev. A | Page 4 of 16

ADP1712/ADP1713/ADP1714 THEORY OF OPERATION SOFT-START FUNCTION (ADP1712) The ADP1712/ADP1713/ADP1714 are low dropout linear regula- tors that use an advanced, proprietary architecture to provide high For applications that require a controlled startup, the ADP1712 power supply rejection ratio (PSRR) and excellent line and load provides a programmable soft-start function. Programmable soft transient response with just a small 2.2 μF ceramic output capac- start is useful for reducing inrush current upon startup and for pro- itor. All devices operate from a 2.5 V to 5.5 V input rail and provide viding voltage sequencing. To implement soft start, connect a small up to 300 mA of output current. Incorporating a novel scaling ceramic capacitor from SS to GND. Upon startup, a 1.2 μA current architecture, ground current is very low when driving light loads. source charges this capacitor. The ADP1712 start-up output voltage Ground current in the shutdown mode is typically less than 1 μA. is limited by the voltage at SS, providing a smooth ramp up to the nominal output voltage. The soft-start time is calculated by T = V ×(C /I ) (1) SS REF SS SS IN OUT where: T is the soft-start period. SS CURRENT VREF is the 0.8 V reference voltage. LIMIT THERMAL CSS is the soft-start capacitance from SS to GND. PROTECT I is the current sourced from SS (1.2 μA). SS SHUTDOWN When the ADP1712 is disabled (using EN), the soft-start capacitor AND UVLO SS/ ADJ/ is discharged to GND through an internal 100 Ω resistor.
