PMIC (Power Management Integrated Circuit ) are a type of ICs used to manage multiple power sources and conditions and control the supply of power to different components in a system. Linear voltage regulators are one of the types of voltage regulators used in a PMIC. They are designed to provide a precise regulated output voltage from a variety of input voltages. The ADP7158ACPZ-2.8-R7 is one such linear voltage regulator and it has several application fields and working principle, which will be discussed in this article.

The ADP7158ACPZ-2.8-R7 is a stepped-down DC-DC regulator with fixed output voltage of 2.8V, input voltage range of 2.5V to 5.5V, and output current capability of up to 1A. It also offers low quiescent current, which ranges from 5μA to 3mA, high ripple rejection and fast transient response. This makes it an ideal choice for applications with low power requirement and a need for clean, stable, and reliable power supply.

It is designed to replace multiple, discrete linear regulators in applications such as: digital cameras, cell phones, MP3 players, PDA and other portable electronics. It can be used in battery-powered devices such as portable computers, digital cameras, personal digital assistants (PDAs) and portable media players. The ADP7158ACPZ-2.8-R7 is also well suited for applications that require tracking or sequencing multiple voltages, including personal computers and automotive systems.

The ADP7158ACPZ-2.8-R7 has a simple three-pin configuration that makes it easy to use. It has an input pin, an output pin, and a ground pin. It is a non-synchronous buck converter, which means that it does not require an external clock signal and is capable of regulating its output voltage without any feedback components. The device is capable of regulating the output voltage regardless of load current and can provide up to 1A of output current.

The ADP7158ACPZ-2.8-R7 operates by using an external resistor to set the output voltage. When the output voltage is set, the internal switch of the device is engaged and the current is allowed to flow into the output pin. When the voltage of the input and output pins become equal, the device switches off and the voltage is maintained at the prescribed level. The device also features over-current and over-temperature protection and is designed for a wide temperature range of -40°C to +85°C.

The ADP7158ACPZ-2.8-R7 linear voltage regulator is a highly efficient device that can provide a reliable and clean power source for low power applications. It is a low cost solution and makes it an ideal choice for cost-sensitive applications. With its wide temperature range, low quiescent current, and high ripple rejection, it is well suited for embedded applications with a need for reliable power management.
