Introduction

TLV713185PDBVT is an adjustable linear three-terminal low dropout (LDO) voltage regulator from Texas Instruments. It features an output voltage adjustable from 0.8V to 10V with a 2.5V reference. It also provides thermal shutdown, current limit and reverse-battery protection. This regulator is best suited for applications requiring low noise, low quiescent current and precise output voltage.

Application Fields

The TLV713185PDBVT is suitable for a wide range of applications, including audio, video, lighting, power management, computing, automotive, communications and other low-power applications. It can be used as a post-regulator in switching power supplies, providing precise, ultra-low noise low voltage regulation. It can also be used to power sensitive telecom and network line cards and provide power for low-power system-on-chip designs.

Working Principle

The TLV713185PDBVT is a linear voltage regulator with an internal reference voltage of 2.5V. The output voltage is controlled by the feedback pin, which is compared to the internal reference voltage and the voltage is applied to the output pin. This voltage is then used to adjust the current flow through the error amplifiers and to the PNP power transistors to maintain the output voltage at the desired level. The current limit on the TLV713185PDBVT is determined by the external resistor which is connected to the current limit pin. This resistor also ensures that the current through the PNP power transistors remains within the safe operating range.The TLV713185PDBVT also has thermal shutdown protection, which is activated when the die temperature exceeds the threshold. This protection is necessary to prevent device failure due to excessive temperature.

Conclusion

In conclusion, the TLV713185PDBVT is a versatile, low noise, low quiescent current adjustable linear voltage regulator from Texas Instruments. It can be used for a variety of low-power applications, and offers protection features such as thermal shutdown, current limit and reverse-battery protection. Its features make it an ideal voltage regulator for audio, video, lighting, power management, computing, automotive, communications and other low-power applications.
