PMIC - Voltage Regulators - Linear

The AP1122EG-U is a linear voltage regulator from Diodes Incorporated, a leading manufacturer of semiconductor products. This device is a low dropout (LDO) voltage regulator capable of supplying up to 2A of current at a voltage of up to 24V. Its low dropout feature makes it ideal for applications that require a wide input range, high efficiency, and low power consumption. It has a wide temperature range and comes with an enable/disable function that can be controlled by an external pin.

The AP1122EG-U has an external enable feature that is set by an external pull-up resistor. When the enable pin is pulled high, the regulator is enabled, while when it is pulled low, the regulator is disabled. This feature can be used to reduce power consumption when it is not needed. In addition, a shutdown line can be used to quickly turn off the device when it is not required.

The AP1122EG-U has a wide operating temperature range and can work from -40°C to +85°C. It also features reverse current protection, current limiting, and over temperature protection, which makes it ideal for use in a wide range of applications. The AP1122EG-U is packaged using DIP 8, standard SO 8 and TSSOP16 packages, making it suitable for a wide range of board types.

Working Principle of the AP1122EG-U

The AP1122EG-U is a linear voltage regulator that works by using a pass transistor to provide a constant output voltage regardless of input voltage or load current. It works by controlling the transistor\'s base voltage with a voltage divider circuit. The voltage divider circuit monitors the output voltage, and if it goes above the desired output voltage, it pulses the base of the transistor to reduce it. Similarly, if the output voltage goes below the desired voltage, the voltage divider pulses the base of the transistor to raise it.

In addition to the voltage divider, the AP1122EG-U also has an output monitoring circuit that ensures a stable output voltage. This circuit monitors the output voltage and can reduce the working frequency if the output voltage goes out of range. The AP1122EG-U also has a current limiting circuit that limits the output current to ensure the safety of the device and the connected equipment.
