Product Overview: TPS74901KTWTG3 by Texas Instruments

The TPS74901KTWTG3 is a high-performance, adjustable, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver precision power management for a variety of applications. This regulator is capable of providing a maximum output current of 3A, making it suitable for powering core voltages of microprocessors, FPGAs, and other digital ICs that require stable and efficient power supplies.

Key Features

• Adjustable Output Voltage: The output voltage of the TPS74901KTWTG3 can be precisely adjusted from 0.8V to 3.3V, allowing for versatile use across multiple devices that require different voltage levels.
• High Accuracy: With an accuracy of ±1%, this regulator ensures reliable and consistent power delivery, which is critical for sensitive electronic components.
• Low Dropout: The low dropout feature enables the regulator to continue providing a stable output even when the input voltage is close to the output voltage, enhancing efficiency and battery life in portable applications.
• Power Good Output: A 'power good' signal is provided to indicate when the output voltage is within its nominal range, which is useful for sequence powering of digital systems.
• Thermal Protection: The device includes built-in thermal shutdown protection that safeguards the regulator and the overall system from overheating.
• Stable with Low-ESR Output Capacitors: The TPS74901KTWTG3 remains stable with ceramic capacitors, which have lower equivalent series resistance (ESR) than other types, thereby reducing output noise and improving transient response.
