Overview of Texas Instruments TPS799285DRVT

The TPS799285DRVT is a high-performance, low-dropout (LDO) linear voltage regulator from Texas Instruments, designed to deliver a stable and reliable power supply for a wide range of applications. This regulator offers a fixed output voltage of 2.85V with an output current capacity of up to 200mA, making it suitable for powering sensitive analog and RF circuits that require a precise and noise-free power source.

Key Features

• High Accuracy: The TPS799285DRVT provides excellent regulation with a low dropout voltage, ensuring a stable output even when the input voltage is close to the output voltage. This is critical for battery-operated devices where maximizing the usable range of the battery voltage is important.
• Low Noise: With an ultra-low output noise of typically 30µVRMS, this LDO is ideal for powering noise-sensitive components such as precision analog-to-digital converters (ADCs), sensors, and RF systems.
• Power-Saving Mode: It features a low quiescent current of typically 40µA in active mode and 1µA in shutdown mode, which is beneficial for portable and battery-powered applications where power efficiency is crucial.
• Thermal Protection: The device includes built-in thermal shutdown protection, which safeguards the regulator and the system from damage due to excessive heat.
• Stable with Low-ESR Capacitors: The TPS799285DRVT is stable with ceramic capacitors, which have lower equivalent series resistance (ESR) than other capacitor types, allowing for a more compact and cost-effective design.
