The ADP7118ARDZ-2.5-R7 is a linear voltage regulator from Analog Devices’ family of PMIC (power management IC) voltage regulators, specifically designed for low voltage, low power applications. The device has a wide input voltage range of 1.8V to 655V, and is capable of providing a regulated output of 2.5V with up to 500mA of output current. It is suitable for various applications including microprocessor cores and other low voltage, low power, applications where high efficiency is not required.The ADP7118ARDZ-2.5-R7 has a typical dropout voltage at the output of 330mV. This allows the device to maintain a regulated output voltage even when the input voltage drops below the output voltage. A built-in low noise, current mode, PWM (pulse width modulation) controller is used to regulate the output voltage. The PWM controller is powered by a regulated voltage derived from the output of the regulator and is used to pulse width modulate the main switching transistor to maintain the output voltage at its set value.An important feature of the ADP7118ARDZ-2.5-R7 is its very low quiescent current of 15μA. This allows the device to be used in portable applications that require very low power consumption. The device also features a low noise bypass mode which provides a smooth transition from continuous conduction mode to discontinuous conduction mode and reduces switching noise on the output. This allows the device to minimize EMI (electromagnetic interference) and minimize the effect on nearby sensitive circuits.The ADP7118ARDZ-2.5-R7 provides the user with a number of protection features that ensure the safe operation of the device and the connected circuits. These include thermal shutdown with hysteresis, over-voltage protection, output current limitation, and short circuit protection.To conclude, the ADP7118ARDZ-2.5-R7 is a linear voltage regulator from Analog Devices’ family of PMIC voltage regulators, specifically designed for low voltage, low power applications. The device provides a regulated output of 2.5V with up to 500mA of output current and a very low quiescent current of 15μA. It also features a low noise bypass mode, thermal shutdown with hysteresis, over-voltage protection, output current limitation and short circuit protection. The device is suitable for a wide range of applications including microprocessor cores and other low voltage, low power applications.
