Working Principle of AP1122EG-13
The AP1122EG-13 is a low dropout (LDO) linear voltage regulator. It features a bridge architecture, with a power transistor on the input side and an output driver MOSFET on the other side. The LDO acts as a current sink, providing low voltage output.When an input voltage is applied to the AP1122EG-13, a voltage is regulated across the output of the device. The output voltage is regulated accurately by varying the gate-source voltage of the MOSFET across the output. This gate voltage is adjusted based on the voltage difference between the input voltage and the output voltage. The AP1122EG-13 operates in a range from 1.22V to 5.5V allowing for a wide range of input and output voltages.The AP1122EG-13 is ideal for low dropout applications and features a very low shutdown current of <1 μA. The device also features a temperature sensing circuit which adjusts the output voltage according to the temperature and a hysteresis voltage which prevents oscillations during transients. The AP1122EG-13 also provides excellent load and line regulation to keep the output voltage within ±1.5% accuracy.The AP1122EG-13 is an efficient device with excellent load and line regulation, making it ideal for high frequency applications like those found in microcontrollers and other digital circuits. The low shutdown current makes the AP1122EG-13 ideal for low power applications.
