TPS79333DBVREP

The TPS79333DBVREP 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 portable devices, battery-powered equipment, and other sensitive electronic circuits.

Key Features:

1. Output Voltage: The TPS79333 is specifically designed to output a fixed voltage of 3.3V. This makes it ideal for powering microcontrollers, sensors, and other digital circuits that require a stable 3.3V supply.

2. Low Dropout Voltage: The LDO features a low dropout voltage, typically around 200 mV at a load current of 100 mA. This characteristic allows it to maintain regulation even when the input voltage is only slightly above the output voltage, which is particularly useful in battery-operated devices.

3. Output Current: The device can deliver up to 200 mA of output current, making it suitable for a range of applications that require moderate power levels.

4. High Power Supply Rejection Ratio (PSRR): The TPS79333 offers excellent PSRR, which helps to minimize the impact of input voltage fluctuations on the output voltage. This is crucial for maintaining stable operation in noisy environments.

5. Low Quiescent Current: The LDO has a low quiescent current, typically around 30 µA, which contributes to improved efficiency in battery-powered applications by reducing power consumption when the device is idle.

6. Thermal Protection: The TPS79333 includes built-in thermal shutdown protection, which prevents damage to the device in case of overheating due to excessive load or insufficient heat dissipation.

7. Package Type: The device is available in a small, thermally efficient DBV package, which is a 5-pin SOT-23 package. This compact form factor is advantageous for space-constrained designs.

8. Operating Temperature Range: The TPS79333 is designed to operate over a wide temperature range, typically from -40°C to +125°C, making it suitable for industrial and automotive applications.

9. Applications: Common applications for the TPS79333 include powering microcontrollers, RF devices, portable electronics, and other applications where a stable 3.3V supply is required.

Electrical Characteristics:

• Input Voltage Range: The device can accept a wide range of input voltages, typically from 2.5V to 5.5V.
• Line Regulation: The TPS79333 exhibits excellent line regulation, ensuring that variations in input voltage do not significantly affect the output voltage.
• Load Regulation: The load regulation is also optimized to maintain a consistent output voltage across varying load conditions.
