TPS71229DRCR

The TPS71229DRCR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. It is designed to provide a stable output voltage with high accuracy and low noise, making it suitable for a variety of applications, including powering sensitive analog and digital circuits.

Key Features:

1. Output Voltage: The TPS71229 is available in a fixed output voltage version, typically providing 2.9V. This fixed output is ideal for applications that require a specific voltage level.

2. Input Voltage Range: The device can accept a wide input voltage range, typically from 2.5V to 6.5V, allowing it to be used in various power supply configurations.

3. Low Dropout Voltage: The LDO features a low dropout voltage, which is the minimum difference between the input voltage and the output voltage required for the regulator to function properly. This characteristic is crucial for battery-powered applications where maximizing battery life is essential.

4. Output Current: The TPS71229 can deliver a maximum output current of up to 200 mA, making it suitable for powering low to moderate load devices.

5. Quiescent Current: It has a low quiescent current, which is the current consumed by the regulator when there is no load. This feature is particularly beneficial in battery-operated devices, as it helps to extend battery life.

6. Thermal Protection: The device includes thermal shutdown protection, which prevents damage due to overheating by shutting down the regulator if the junction temperature exceeds a certain threshold.

7. Package Type: The TPS71229DRCR is offered in a small, thermally enhanced DRC package, which is a 3mm x 3mm QFN (Quad Flat No-lead) package. This compact size is advantageous for space-constrained applications.

8. Noise Performance: The LDO is designed to provide low output noise, which is critical for applications that require clean power, such as RF and precision analog circuits.

9. Power Supply Rejection Ratio (PSRR): The TPS71229 exhibits a high PSRR, which indicates its ability to suppress variations in the input voltage, ensuring a stable output voltage even in the presence of input voltage fluctuations.

Applications:

The TPS71229DRCR is suitable for a variety of applications, including:
