Introduction

TLV70243DSER is a linear voltage regulator (LVR) designed by Texas Instruments. This LVR is a positive voltage regulator with a voltage range of 20V-65V. It is a three-terminal adjustable device with an internal pass transistor for output current up to 1.5A. Besides its adjustable output voltage, TLV70243DSER offers excellent regulation performance, low quiescent current, and minimum dropout voltage.

Application Field

TLV70243DSER is suitable for applications that require adjustable output voltage. Its wide input voltage range makes it especially suitable for automotive systems where the battery voltage can go as high as 50V due to voltage surges. Highway trucks and electric vehicles are good examples of applications that may use TLV70243DSER.

Working Principle

TLV70243DSER operates by comparing the voltage of the output and the reference. When the output voltage differs from the reference, the LVR will adjust the bias current to the pass transistor accordingly to getting closer to the desired output voltage.The TLV70243DSER features protection features such as a programmable overcurrent limit, temperature shutdown, and over temperature protection. This provides robust protection for the device and its load.The TLV70243DSER also has a low quiescent current, which helps to reduce power dissipation and save power in the system. A low dropout voltage also helps to ensure smooth regulation performance at low output voltages.

Conclusion

TLV70243DSER is a linear voltage regulator designed by Texas Instruments. It is ideal for applications that require an adjustable output voltage and offers robust protection, low quiescent current, and a low dropout voltage. This LVR is suitable for automotive applications where battery voltages can range as high as 50V.
