Linear & Switching Voltage Regulators

The TPS73701DRBR is a low-power, low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments. This device is designed to provide a stable and reliable voltage output for a wide range of applications, including battery-powered systems and portable electronics.

Description:

The TPS73701DRBR is a compact, 10-pin, 1.2mm x 1.2mm WQFN package. It features an input voltage range of 1.9V to 5.5V and can deliver an output current of up to 500mA. The device has a very low dropout voltage (typically 160mV at 500mA), which makes it suitable for battery-powered applications where minimizing power consumption is critical.

Features:

1. Low quiescent current: 2.5μA (typical), which helps to extend battery life in portable devices.
2. Low dropout voltage: 160mV (typical) at 500mA output current, ensuring stable output voltage even under heavy load conditions.
3. Wide input voltage range: 1.9V to 5.5V, making it suitable for various power supply scenarios.
4. Small package size: 1.2mm x 1.2mm WQFN, which saves board space and is suitable for compact designs.
5. Enable pin functionality: Allows for easy control of the regulator's operation.
6. Thermal shutdown protection: Protects the device from overheating in case of excessive current or short-circuit conditions.
7. Fixed output voltage options: Available in various output voltages, such as 1.8V, 2.5V, 3.3V, and others, to suit different application requirements.

Applications:

1. Portable electronics: Smartphones, tablets, and wearable devices, where low power consumption and small form factor are essential.
2. Battery-powered systems: Medical devices, remote sensors, and IoT devices, where extended battery life is crucial.
3. Automotive electronics: Infotainment systems, GPS units, and other in-vehicle electronics that require stable voltage regulation.
4. Industrial control systems: Microcontrollers, sensors, and other components that require a stable power supply in harsh environments.
5. Consumer electronics: Cameras, audio equipment, and other devices that require low-noise voltage regulation for optimal performance.

In summary, the TPS73701DRBR is a low-power, low-dropout linear voltage regulator that offers a compact solution for a wide range of applications, particularly in battery-powered and portable electronics. Its low quiescent current, low dropout voltage, and small package size make it an ideal choice for designs where power efficiency and space constraints are critical.
