Overview
The TPS7360IDBVR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. It is designed to provide a stable output voltage with minimal dropout, making it suitable for battery-powered and precision electronic applications. The device comes in a compact SOT-23-5 package, ideal for space-constrained designs. With a typical dropout voltage of 150 mV at 150 mA, the TPS7360IDBVR ensures efficient power conversion. It also features low noise output and high power supply rejection ratio (PSRR), which are critical for sensitive analog and digital circuits.
Structure and Working Principle
The TPS7360IDBVR consists of a voltage reference, error amplifier, pass transistor, and protection circuitry. The error amplifier compares the output voltage to a precision reference and adjusts the pass transistor to maintain the desired output voltage. The device operates by regulating the input voltage to a fixed output voltage, even when the input voltage fluctuates. Its low dropout characteristic allows it to function efficiently even when the input voltage is only slightly higher than the output voltage, conserving energy in battery-operated systems.
Key Features
Key features of the TPS7360IDBVR include a low dropout voltage of 150 mV (typical) at 150 mA load, high accuracy (±1% over temperature), and low quiescent current (typically 40 µA). These attributes make it suitable for portable and power-sensitive applications. The regulator also includes built-in thermal shutdown and current limit protection, ensuring reliable operation under adverse conditions. Its small footprint and minimal external component requirements simplify PCB design and reduce overall system cost.
Application Areas
The TPS7360IDBVR is widely used in portable electronics, IoT devices, medical equipment, and industrial control systems. Its precision and low noise characteristics make it ideal for powering sensitive analog circuits, such as sensors and RF modules. In addition, the regulator is commonly employed in battery-powered applications, including wearables and handheld devices, where energy efficiency and stable voltage supply are critical for prolonged operation.
Maintenance and Precautions
To ensure optimal performance, avoid exposing the TPS7360IDBVR to input voltages exceeding its maximum rating (6 V). Proper heat dissipation should be considered in high-current applications to prevent thermal shutdown. When designing the PCB, place decoupling capacitors close to the input and output pins to minimize noise and improve stability. Follow the manufacturer's guidelines for layout and component selection to achieve the best performance.
B2B Procurement Guide
When procuring the TPS7360IDBVR in bulk, verify the supplier's authenticity to avoid counterfeit components. Texas Instruments and authorized distributors are recommended sources for genuine parts. Consider lead times and minimum order quantities (MOQs) when planning purchases. For large-volume orders, negotiate pricing and explore long-term supply agreements to secure cost savings and reliable inventory.
