The TPS7A05285PDBVR is a linear voltage regulator from Texas Instruments dedicated to providing a stable and accurately regulated voltage supply. It belongs to the family of Pin-programmable Regulators for Fixed Output Voltages, and is ideal for a wide variety of applications. It features an extremely low Iq voltage of 0.85mA, as well as highly efficient thermal performance and low noise operation.

The TPS7A05285PDBVR is designed to operate in the range of 2.1V to 5.5V input. It also includes a feature known as Pin-programmable Integrated Soft-Start, which offers superior transient response and improved inrush current control during startup. It also has a wide operating temperature range of -40°C to +125°C. This device is built with an internal 2.4A peak current limit and an internal thermal shutdown.

This device has multiple applications, such as in portable electronics, instrumentation equipment, handheld transmitters, digital cameras, tablets, and audio/video devices. It can also be used to power bipolar and CMOS devices, as well as DRAM, EPROM, Flash, FPGA and TMR memories.

The TPS7A05285PDBVR provides excellent load and line regulation, and can provide up to 1.5A of output current. Its PSRR (Power Supply Rejection Ratio) is high, with a minimum of 75 dB at 10kHz. It provides high immunity to EMI and has high isolation between input and output, with the typical breakdown voltage between 28V to 34V.

The working principle of the TPS7A05285PDBVR is based on the concept of a series regulator. A series regulator is a device that controls and regulates the output voltage by continuously monitoring the load current and adjusting the device\'s conductivity to maintain the desired voltage. This is done by using an internal voltage reference or power amplifier, which compares the output voltage of the device to the reference voltage, and adjusts the current accordingly.

The internal voltage reference of the TPS7A05285PDBVR is derived from a low-power and low-noise external resistor network. Internal current regulation is focused on the output stage, which allows to the device to maintain stability and accuracy, even under high-current conditions. This makes it suitable for use in applications that require high accuracy and stability.

The TPS7A05285PDBVR is an ideal choice for applications requiring regulated and stable supply voltages. It is easy to set-up and configure, and offers low power consumption and high efficiency. With its exceptional thermal and electrical performance, the device is suitable for many different applications.
