TLV7041DPWR

The TLV7041DPWR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. It is designed to provide a stable output voltage with high efficiency and low quiescent current, making it suitable for battery-powered applications and other scenarios where power conservation is critical.

Key Features:

1. Output Voltage Options: The TLV7041 is available in various fixed output voltage options, typically including 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, and 3.3V. This allows designers to select the appropriate voltage for their specific application needs.

2. Low Dropout Voltage: The device features a low dropout voltage, typically around 200 mV at a load current of 1 A. This characteristic enables the regulator to maintain a stable output voltage even when the input voltage is close to the output voltage, which is particularly useful in battery-operated devices.

3. High Output Current: The TLV7041 can deliver up to 1 A of output current, making it suitable for a wide range of applications, from powering microcontrollers to driving sensors and other peripherals.

4. Low Quiescent Current: With a quiescent current of only a few microamperes, the TLV7041 is ideal for low-power applications, helping to extend battery life in portable devices.

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

6. Compact Package: The TLV7041DPWR is housed in a small, thermally efficient PowerPAD™ package, which helps to minimize the overall footprint on the PCB while providing effective heat dissipation.

7. Power Supply Rejection Ratio (PSRR): The regulator exhibits a high PSRR, ensuring that variations in the input voltage do not significantly affect the output voltage, which is crucial for sensitive analog circuits.

8. Stability with Low ESR Capacitors: The TLV7041 is designed to work with low equivalent series resistance (ESR) ceramic capacitors, which are commonly used in modern electronic designs for their size and performance characteristics.

Applications:

The TLV7041DPWR is suitable for a variety of applications, including:

• Battery-powered devices
