TPS76715QPWPG4 Application Field and Working Principle
A voltage regulator, or a linear voltage regulator, is an important component for applications requiring a stable output voltage with limited output current. Commonly used in switch mode power supplies and cell phone power management, voltage regulators provide a constant voltage to keep equipment running in a stable condition. The Texas Instruments TPS76715QPWPG4 is a low dropout (LDO) regulator offering low dropout voltage (at 370mV), low quiescent current (< 60uA) and high output current(up to 1.8A).
TPS76715QPWPG4 Specifications
The TPS76715QPWPG4 is a high-performance, low dropout (LDO) voltage regulator with a wide input voltage range from 2.5V to 5.5V, selectable output voltage from 1.8V to 3.3V for output current up to 1.8A. It is especially well suited for applications requiring output voltage and very low dropout, such as those powered from Li+ battery systems. The regulator is rated for power dissipation of up to 280mW over an operating temperature range of -40°C to 85°C. It has a maximum of 300mV output noise, and a ±2% output accuracy.
TPS76715QPWPG4 Application Field
The TPS76715QPWPG4 is suitable for a variety of applications requiring a stable output voltage with high output current. Typical applications include Li-Ion battery powered portable devices such as cell phones, PDAs, digital cameras, portable audio players, mobile data terminals and automotive applications, as well as other applications requiring a regulated low dropout voltage, such as computer peripherals, communications devices and low voltage components.The low dropout (LDO) regulator can also be used for applications requiring high efficiency and power for DC/DC converters, voltage references, and automotive systems.
TPS76715QPWPG4 Working Principle
The TPS76715QPWPG4 is a low dropout (LDO) voltage regulator with very low dropout voltage (at 370mV) and low quiescent current (< 60uA). Its design reduces power consumption and optimizes current control for low-noise operation. The regulator provides an internal foldback current and temperature protection which prevents damage due to excessive load or temperature.The device also features a high output accuracy with a wide input voltage range and selectable output voltage. This device operates in PWM mode or pulse-skipping mode to minimize noise and improve efficiency. The internal circuit design also provides a very low output impedance (described by an effective On resistance, RON) which helps reduce output voltage fluctuations due to changes in load or temperature.
Conclusion
The Texas Instruments TPS76715QPWPG4 is a high-performance, low dropout voltage regulator with a wide input voltage range from 2.5V to 5.5V, selectable output voltage from 1.8V to 3.3V for output current up to 1.8A. Its low power consumption, low noise and high efficiency makes it suitable for a variety of applications like cell phones, PDAs, digital cameras and portable audio players. The design of the TPS76715QPWPG4 also provides a low output impedance and protection from excessive loads, making it the ideal solution for applications requiring a stable output voltage.
