ADP7118AUJZ-2.5-R7 is a linear voltage regulator manufactured by Analog Devices. It is a low-to-medium current, low dropout (LDO) regulator designed to work with input voltages from 1.8V to 5.5V and output voltages of 2.5V. The device offers excellent line and load regulation, low quiescent current and high power supply rejection ratio. ADP7118AUJZ-2.5-R7 has a wide range of application fields, which include portable communications and computing applications, consumer electronic devices and automotive applications.

ADP7118AUJZ-2.5-R7 is based on a voltage regulator chip, which is a three-terminal integrated circuit that regulates the voltage from its input to its output. The chip comprises transistors, resistors and capacitors, along with additional components, to perform the voltage-regulating function. It ensures that whatever voltage is applied at the input is maintained at the output. A voltage regulator chip has two main components: a voltage reference circuit, which is determined by the power supply and a power switch, which is determined by the load condition.

The ADP7118AUJZ-2.5-R7 operates in a three-mode regulation where an output voltage is obtained through series, shunt, or a combination of both modes. The series mode connect the output voltage to the input voltage through a series of resistors and capacitors. During the shunt mode the current is shunted away from the load when the output voltage reaches the set point, so the regulator can maintain the pre-determined output voltage. This device also has a low-noise, low-drop-out performance due to which the output voltage remains stable even when the input supply voltage is fluctuating.

The ADP7118AUJZ-2.5-R7 voltage regulator provides over-voltage, over-load and thermal protection. It has a supply current of 5 mA and a dropout voltage of 260 mV at 2A output current. The device can operate over a temperature range of -40°C to +85°C, which makes it suitable for a wide range of applications.

In summary, the ADP7118AUJZ-2.5-R7 is a low-to-medium current, low dropout linear regulator that operates in a three-mode regulation. It offers excellent line and load regulation, low quiescent current and high power supply rejection ratio. The device has a wide range of application fields, including portable communications and computing applications, consumer electronic devices and automotive applications. Furthermore, it provides over-voltage, over-load and thermal protection and can operate over a temperature range of -40°C to +85°C, which makes it suitable for a wide range of applications.
