The TPS74201RGWR is a low-dropout (LDO) linear voltage regulator designed for applications requiring ultra-low quiescent current. It is part of Texas Instruments’ power management integrated circuit (PMIC) range and is categorized as a Voltage Regulator - Linear. It is built with a wide input range, featuring excellent power supply rejection, ultra-low quiescent current and dropout voltage, as well as very tight output accuracy. This also ensures a high output accuracy over temperature, load current and frequency shifts. This article will focus on the application field and working principle of the TPS74201RGWR.

Application Field of TPS74201RGWR

The TPS74201RGWR is ideal for applications requiring ultra-low quiescent current, such as those involving battery-powered products and applications in which active-mode current must be minimized. Typical applications for the TPS74201RGWR can be found in digital cameras, cell phones, medical devices, handheld instruments, transportation electronics and portable POS systems. In addition, it can be used in applications where space is limited, such as in automotive infotainment, monitoring and portable battery systems.

Working Principle of TPS74201RGWR

The TPS74201RGWR is a low-dropout (LDO) linear voltage regulator designed to allow output voltages as low as 1.2V with input voltages up to 5.5V. The device’s low-dropout feature makes it the ideal choice for applications with large voltage differences between the input and the output. Its low quiescent current feature also makes it ideal for portable applications and systems with active mode current requirements. In addition, the TPS is built with excellent power supply rejection for clean, reliable output voltage.

The TPS74201RGWR also features a protection circuit that includes output current limit protection, over-temperature protection, reverse battery protection, and built-in self-protection. This protection circuit helps to protect the device and the connected electronics from damage that could be caused by extreme input and output conditions. The maximum output current of the device is 150mA.

The TPS74201RGWR operates as an adjustable voltage regulator in Series or Parallel Negative voltage regulator mode. It has a feedback voltage loop control, which allows users to adjust the output voltage quickly and easily. The device can be enabled or disabled with an active-high enable pin, which has an open drain logic with an output pull-up resistor off-board. The device is also built with a fast transient response and voltage settling time. This helps the device to recover quickly after a sudden change in output voltage.
