TLV71310PDBVT Application Field and Working Principle

TLV71310PDBVT is a high performance power management IC (PMIC), specifically targeting low voltage applications such as digital camera, portable navigation systems and other consumer applications. The concept of the voltage regulator and its function is described in more detail below.

What are Voltage Regulators and What is their Function?

A voltage regulator is designed to keep a regulated output given from an unstable or fluctuating input. Voltage regulators maintain a given voltage level and prevents the changes in the output when the input changes. Voltage regulators are typically used in electronic devices to provide consistent power for their internal components. The output voltage is controlled by the voltage regulator, often through a feedback loop.

Linear Voltage Regulators

Linear voltage regulators are the most widely used form of voltage regulators and use integrated circuits. This type of voltage regulator utilizes a series of resistors and transistors to step down the input voltage and maintain a given output voltage. The linear voltage regulator works by limiting the output voltage to a fixed value regardless of the input voltage.

TLV71310PDBVT is a linear voltage regulator, specifically tailored for low voltage applications. The device is a variable output voltage regulator that offers a wide input and output range making it applicable to a wide range of consumer applications. The TLV71310PDBVT can provide up to 0.8A output current and has an adjustable output voltage between 0.9V and 5.0V. The input voltage range is 2.7V to 5.5V and features a 300mV dropout voltage with 0.8A of load current. It is designed using high performance transistors to ensure a high switching speed and low quiescent current. The TLV71310PDBVT is designed using high performance transistors to ensure a high switching speed and low quiescent current consumption. The device also features programmable over temperature, current limit protection and under voltage lock out (UVLO).

TLV71310PDBVT Application Fields

The TLV71310PDBVT is ideal for use in a variety of low voltage consumer applications including digital cameras, portable navigation systems, gaming consoles and portable audio/video players. Its simple CCM architecture allows it to provide excellent transient response and high efficiency performance. Its wide input and output voltage range enables it to be used in both portable and desktop applications. Additionally, its low quiescent current consumption makes it well suited for battery powered applications.

TLV71310PDBVT Working Principle

The TLV71310PDBVT is a linear regulator and works by driving a series pass element with a voltage that is regulated based on the voltage at the output of the regulator. The TLV71310PDBVT has two pins, Input and Output, and a control pin. This control pin can be adjusted to adjust the output voltage, hence the name “adjustable output voltage regulator”. The Input pin supplies the input voltage that is to be regulated while the output pin supplies the regulated output voltage. The TLV71310PDBVT has an internal low quiescent current, load switch, which is switched on when the output voltage is below a certain level. This ensures that the output voltage is always steady and does not fluctuate due to changes in the input voltage. The device also has a programmable over temperature, current limit protection and under voltage lock out (UVLO) feature that prevents any unwelcome surges or under voltage scenarios. This feature also helps to protect the device from thermal damage caused by excessive current or voltage.

Conclusion

TLV71310PDBVT is a high performance linear voltage regulator specifically designed for low voltage applications. The device’s wide input and output voltage range, as well as its programmable over temperature, current limit protection and under voltage lock out (UVLO) allows it to be used in a variety of consumer applications. The device allows a regulated output to be maintained given an unstable input voltage and is ideal for use in digital cameras, portable navigation systems, gaming consoles and portable audio/video players.
