TPS76038DBVR Voltage Regulator
Introduction
The TPS76038DBVR is an integrated positive-voltage linear regulator with ultra-low output voltage noise, high PSRR and convenient enable control. Operating as a 5-V and 3.3-V output linear regulator, the TPS76038DBVR is designed to power FPGAs, DSPs, controllers, and SRAMs.Features
The major features of the TPS76038DBVR include:- Wide input voltage range of 2.7V–6V
- Ultralow output voltage noise
- Internal overcurrent and overtemperature protection
- Flexible enable control
- Rated output current of 250 mA
- High PSRR of up to 40 dB
- High output linearity
Applications
The TPS76038DBVR is well suited for a wide range of applications, such as embedded systems that require precision voltage regulation for microprocessors, DSPs, FPGAs, and SRAMs. Additionally, it is ideal for low-power set-top box, digital TV, power-management systems, and industrial control applications, where its low-output-voltage noise and high PSRR ensure excellent regulation.Working Principal
Using a low-noise error amplifier, a voltage reference, and a power MOSFET, the TPS76038DBVR provides high-efficiency voltage regulation. A PMOS pass transistor is connected before the voltage reference to connect or disconnect the output to the load. When enabled, the error amplifier compares the differential signal between the output voltage and an internal reference voltage to generate an appropriate voltage signal to the associated gate at the PMOS pass transistor. The pass transistor will then adjust its overdrive voltage according to this signal to maintain the output voltage at the desired level.Conclusion
The TPS76038DBVR offers an efficient, low-cost solution for high-precision voltage regulation in a small package for a variety of applications. With its high PSRR, low-noise output voltage, and comprehensive enable control, the device provides the perfect balance of high performance and small form factor.The specific data is subject to PDF, and the above content is for reference
