Introduction
The TPS7A4501U/EM is a low dropout (LDO) linear voltage regulator. It is one of Texas Instruments\' LDO family of linear voltage regulators and specifically, the TPS7A4500-Q1 (Q1) series. LDOs have a wide variety of applications in automotive, industrial, and consumer electronics.Application Field
The TPS7A4501U/EM is designed to provide post-processing voltage regulation in automotive designs. It is a perfect solution for pre-processing power supplies in a power distribution network and line-voltage regulation circuitry. It is ideal for providing post-regulation voltages in automated systems with high thermal design power (TDP) requirements. The device can also be used for post-processing voltage regulation against transients and disturbances.Working Principle
The TPS7A4501U/EM is a low dropout (LDO) linear voltage regulator. Its working principle is to reduce the input voltage to the regulated output voltage via a series of resistors to limit the current. The linear voltage regulator then maintains constant output voltage and current by adjusting the output voltage as needed to match the given input voltage. The linear voltage regulator is configured by a couple of external components, including an error amplifier, a comparator, and a set of resistors.The TPS7A4501U/EM has two separate voltage regulators, which are capable of operating in parallel mode for smooth and accurate output voltages, even for high output currents. The device features adjustable output voltage and ±3% accuracy over temperature, ensuring the most precise voltage regulation. The device uses external components to create a control loop, enabling it to maintain output voltage at all times.The device has a quiescent current of only 5µA, making it very efficient for battery operated applications. It also features overcurrent and thermal protection features to further ensure reliability and stability of the output voltage. Moreover, the TPS7A4501U/EM is characterized for operation from -40°C to +85°C.Conclusion
The TPS7A4501U/EM is a low dropout (LDO) linear voltage regulator designed to provide post-processing voltage regulation in automotive designs. It is capable of maintaining the output voltage at all times, and offers efficient operation with a quiescent current of only 5µA. Its applications include pre-processing power supplies in power distribution networks, line-voltage regulation circuitry, and post-regulation voltages in automated systems with high TDP requirements. The device is also characterized for operation from -40°C to +85°C, and features adjustable output voltage and ±3% accuracy over temperature.The specific data is subject to PDF, and the above content is for reference
