Overview of Texas Instruments TPS76633DR

The TPS76633DR from Texas Instruments is a highly reliable, low-dropout (LDO) voltage regulator designed for applications requiring a low-power, stable voltage source. This efficient component is ideal for power-sensitive devices, providing a fixed output voltage of 3.3V with an accuracy of ±2% over temperature, line, and load variations.

Key Features

• Low Dropout Voltage: The TPS76633DR offers a low dropout voltage, typically 250mV at 250mA load, which ensures efficient operation even when the input voltage is close to the output voltage.
• High Output Current: Capable of delivering a continuous output current of up to 250mA, this LDO regulator can power a wide range of components and systems.
• Thermal and Overcurrent Protection: Built-in thermal shutdown and overcurrent protection features safeguard the device and the system from damage due to excessive heat and load conditions.
• Low Quiescent Current: The TPS76633DR maintains a low quiescent current of 85µA (typical) in operation and less than 1µA in shutdown mode, making it suitable for battery-powered applications.
• Stable with Low ESR Capacitors: This voltage regulator is stable with ceramic capacitors, which have lower equivalent series resistance (ESR) than tantalum or aluminum electrolytic capacitors, providing improved performance and reliability.

Applications

The TPS76633DR is versatile and can be used in various applications, including:

• Portable Devices
• Battery-Powered Equipment
• Microcontroller Power Supply
