Overview
The TPS79428DGNT is a high-performance, low-dropout (LDO) voltage regulator produced by Texas Instruments. Designed for a wide variety of applications, it offers clean, precise voltage regulation, which is highly valued particularly in sensitive electronic devices. Its utilization of MicroStar Junior packaging makes it compact and efficient, suitable for integration into various systems.
Key Features
Some of the most important features of the TPS79428DGNT are its low dropout voltage, high accuracy, and exceptional Power Supply Rejection Ratio (PSRR). It also boasts low noise and low quiescent current, ensuring minimal interference and power drain. The device's ability to operate over a wide temperature range, from -40°C to 125°C, makes it versatile for different environments. Furthermore, it includes a thermal shutdown and overcurrent protection system to avoid overheating and other potential damages.
Technical Specifications
This LDO regulator has an output voltage range of 2.2V to 5.5V and an output current of up to 250mA. The quiescent current is as low as 17μA at full load, contributing to its energy-saving benefits. The PSRR is 73dB at 1kHz, which means it has an exceptional ability to smooth out ripple and noise from the input voltage. The noise output is also impressively low, at only 33μVRMS.
Applications
The TPS79428DGNT is designed for general purpose use, including in handheld devices, notebook PCs, and other portable electronics due to its small size and high efficiency. It is also suitable for use in telecommunications and networking equipment, industrial control systems, and other high-performance digital systems, where precise power regulation under fluctuating conditions is paramount.
