Introduction

The TLV70218DBVR is an integrated voltage regulator that is specifically designed for precision applications. It is a low dropout linear regulator with a low output voltage accuracy of ±1.5%. The TLV70218DBVR’s design is optimized for single-supply operation and to provide a high degree of stability and regulation performance.

Application Fields

The TLV70218DBVR can be used in precision analog and digital circuits that require stable voltage outputs and low dropout power supplies. Some of the application fields include:

• Telecommunication systems
• Data processing systems
• Computer systems
• Battery-powered devices
• Automotive applications
• Industrial instruments
• Medical devices
• Sensor networks

Features

The TLV70218DBVR is a high-performance adjustable linear voltage regulator that offers a wide range of features for efficient power delivery in precision analog and digital applications. Some of these features include:

• High precision voltage output accuracy (±1.5%)
• Low quiescent current of 4.2 mA (maximum)
• Low dropout voltage (1 V typ at 1 A load current)
• High power supply rejection ratio (100 dB min)
• Wide operating temperature range (−40°C to +125°C)
• Operation over wide input voltage range (2 V to 40 V)
• Short circuit protection, overvoltage protection, reverse current protection and thermal shutdown protection
• A shutdown feature that reduces supply current to 40 μA (typical) when the regulator is shut down
• Thermal shutdown protection that shuts down the regulator when the junction temperature exceeds 150°C
• Lead (Pb) free and halogen free package options

Working Principle

The TLV70218DBVR is a linear voltage regulator, which means it works on the principle of converting the input voltage to the output voltage based on the difference between them. The primary function of the regulator is to maintain a steady output voltage regardless of fluctuations in variable input voltage and load current up to 1.5 A.The TLV70218DBVR operates with an input voltage range of 2 V to 40 V, and uses a high precision voltage reference to ensure a constant output voltage with a tolerance of ±1.5%. The output voltage can be adjusted, via an external resistor, to either higher or lower values up to a limit of 27 V. The output current is limited to a maximum of 1.5 A by virtue of the power transistor circuit and current limiting diode.The TLV70218DBVR also includes a slew rate limited inrush current limiter and a power switch to reduce power consumption during enable and disable operations. Additionally, the regulator includes a thermal shutdown protection feature that can be enabled via a pin, and activated when the die temperature exceeds 150°C.

Conclusion

The TLV70218DBVR integrated voltage regulator is designed for precision applications, including telecommunication systems, data processing systems, computer systems, battery-powered devices, automotive applications, industrial instruments, medical devices, and sensor networks. Its low dropout voltage and wide operating temperature range make it especially suitable for very low power applications. Its integrated features such as inrush current limiter, enable/disable control, and thermal shutdown protection also make it a reliable and versatile option.
