ADP1752ACPZ-1.1-R7 Application Field and Working Principle

The ADP1752ACPZ-1.1-R7 is a linear voltage regulator (LVR) from Analog Devices and falls into the Power Management IC (PMIC) category. This device provides voltage regulation and electromagnetic interference (EMI) filtering for systems that require efficient, high current supplies. This LVR is available in an industry-standard 2.5 mm x 4 mm SOT-23-5 surface-mount package.

The ADP1752ACPZ-1.1-R7 is designed to provide an input voltage of 2.5 V up to 6 V and an adjustable output voltage from 0.8 V up to the input voltage. Its high efficiency allows it to operate over an extended temperature range from -40°C to +125°C. This LVR also includes a built-in circuit protection to shut off the output in the event of an over-temperature or short-circuit condition.

The main functional blocks of this device include four main components: the VIN pin, the regulating control circuit, the reference voltage generator, and the feedback circuit. The VIN pin is typically connected to the input voltage source. The regulating control circuit can be used to implement various control functions such as a power-on reset, a voltage maintanence circuit, a line regulation circuit, and a frequency doubler. The reference voltage generator provides the output voltage through an error amplifier, while the feedback circuit is responsible for sensing the output voltage and adjusting the controlling parameters accordingly.

The operating principle for the ADP1752ACPZ-1.1-R7 is straightforward. When the input voltage is greater than the output voltage, the regulator will begin to reduce the current through the load, causing the output voltage to decrease. This process will continue until the output voltage equals the input voltage, at which point the regulating control circuit will eliminate the current through the load, thus allowing the output voltage to remain stable.

The ADP1752ACPZ-1.1-R7 is an efficient and highly reliable device designed for a wide range of applications, such as industrial systems, power supplies, computers and communication equipment, automotive and white goods. In addition, the device can be used to provide voltage regulation and EMI filter in any application that requires a stable and regulated output voltage. It can also be used to provide input to step-down converters and other power management / voltage regulation devices.

Overall, the ADP1752ACPZ-1.1-R7 is a highly efficient and reliable linear voltage regulator. It offers excellent performance over a wide temperature range and a wide array of features ideal for a range of applications. The device can provide input power to a variety of electronic systems, while at the same time providing an output voltage that can be adjusted to suit any application requirements.
