Introduction to TLV2217-25PWG4

The TLV2217-25PWG4 is a high-precision, low dropout linear regulator from Texas Instruments’ TLV family of linear voltage regulators. It is designed to provide up to 25V of regulated output voltage in a single package. This voltage regulator is easy to configure and provides excellent guaranteed output performance.

TLV2217-25PWG4 Application Field

The TLV2217-25PWG4 is ideally suited for use in applications requiring up to 25V of regulated output. This makes it well-suited for a variety of applications, including industrial, medical, and telecommunications. Additionally, this voltage regulator is designed to meet the needs of low supply current and low noise operation, making it suitable for battery powered applications.

TLV2217-25PWG4 Working Principles

The TLV2217-25PWG4 is a voltage regulator based on a low dropout linear architecture. This design is based on a series pass configuration, where power is regulated by controlling the resistance between the input and output of the regulator. This resistance is controlled by a feedback loop. The voltage across this controlled resistance is compared to a reference voltage, and an error signal is generated that is used to modify the resistance and maintain a regulated output voltage.The TLV2217-25PWG4 features an Internal Thermal Over-Current Protection (ITOCP) circuit which detects and limits load current if an overload condition is detected. This ensures that the voltage regulator is protected from thermal overloads. Additionally, it features short cirucit protection and thermal shutdown protection, ensuring that the device is protected from damage if there is an excessive load on the device.

Conclusion

The TLV2217-25PWG4 from Texas Instruments’ TLV family of linear voltage regulators is an excellent solution for applications requiring up to 25V of regulated output. Its low dropout linear architecture ensures low supply current and low noise operation, making it an ideal solution for battery powered applications needing accurate and reliable regulation. The regulated output performance is guaranteed by an Internal Thermal Over-Current Protection (ITOCP) circuit, short circuit protection, and thermal shutdown protection.
