TLV75519PDQNR Application Field and Working Principle
TLV75519PDQNR is a linear voltage regulator from Texas Instruments that integrates a series pass architecture with minimum external components, a built-in reference voltage and a variety of error-compensation features for a fast, efficient and highly-accurate power supply design. It provides excellent performance, low quiescent current, low noise and low dropout voltage in a wide range of application fields. It is suitable for 1- or 2-cell Li+ based sources as well as 2- to 5-cell NiCd or NiMH-based sources.
Overview
This device is a micropower linear voltage regulator designed to operate from 1.7 V to 5.5 V, with an adjustable output voltage from 0.7 V to 5.5 V. It offers accurate output voltage regulation, low quiescent current, quick response to load and temperature changes, and low operating temperature range. With the minimum operating power supply voltage of 1.7 V, the TLV75519PDQNR can be used in wide range of low voltage applications. The external components requirement for many applications is extremely small and complex designs can easily be implemented.
Applications
The TLV75519PDQNR is suitable for a wide range of applications, including peripheral voltage supply for microcontrollers and other digital components, DSP\'s, audio amplifiers, cellular phones, and digital cameras. It is also suitable for portable medical devices, such as body monitors, digital thermometers, medical carts, and vital sign monitoring devices. Other applications include direct input battery-powered digital systems, extending battery life, and providing accurate voltage regulation in low quiescent current circuit designs.
Features
This device has several features including an adjustable output voltage range from 0.7 V to 5.5 V and low quiescent current of 8 µA. It also offers an adjustable voltage accuracy of ±2%, a sink current of 8 mA and a maximum output current of 500 mA, enable and shutdown control, a positive temperature coefficient of voltage, and a low dropout voltage of 0.75 V. The wide voltage range of operation allows the device to be used in wide range of low voltage applications. The output voltage can also be adjusted externally enabling the user to optimize the performance for specific application.
Working Principle
The TLV75519PDQNR consists of two parts: an internal reference voltage and an error amplifier. The reference voltage is used to convert a low voltage input into a higher output voltage and the error amplifier monitors the output voltage to ensure that the output voltage is always maintained at the desired level. The error amplifier compares the output voltage to a reference voltage and adjusts the output current based on the difference. The output current is increased when the output voltage is lower than the reference voltage and decreased when the output voltage is higher than the reference voltage. This ensures that the output voltage remains at the desired level. The TLV75519PDQNR also integrates several compensation features that allow it to respond quickly to load and temperature changes. It also has a shutdown mode and an enable pin that can be used to control the device from an external source.
Conclusion
The TLV75519PDQNR is an excellent linear voltage regulator from Texas Instruments that is suitable for a wide range of low voltage applications. It provides excellent performance, low quiescent current, low noise, and low dropout voltage in a wide range of application fields. It is a suitable choice for designers who require accurate voltage regulation in low quiescent current circuit designs.
