The TPS76633D is a highly reliable, low-dropout (LDO) voltage regulator designed by Texas Instruments (TI), specifically engineered to deliver a stable and clean power supply. This regulator is capable of providing an output current of up to 250 mA while maintaining a low dropout voltage, making it an excellent choice for power-sensitive applications.

Key Features

• Output Voltage: The TPS76633D offers a fixed output voltage of 3.3V, which is ideal for powering 3.3V logic in a variety of electronic systems.
• Low Dropout: With a typical dropout voltage of just 230 mV at full load, it ensures efficient operation even when the input voltage is close to the output voltage, reducing power loss and improving overall system efficiency.
• High Accuracy: This LDO features an excellent output voltage accuracy of ±2%, which contributes to the reliable operation of sensitive electronic components.
• Thermal Shutdown and Overcurrent Protection: The TPS76633D incorporates built-in thermal shutdown and overcurrent protection features that safeguard the device and the system from damage due to excessive heat and current conditions.
• Low Quiescent Current: It boasts a low quiescent current of just 85 µA, making it suitable for battery-powered devices where power conservation is critical.
• Stable with Low ESR Capacitors: The regulator is stable with ceramic capacitors, which have lower equivalent series resistance (ESR) than tantalum or aluminum electrolytic capacitors, providing better transient response and reliability.
