Infineon TLS805B1LDV50: The 50mA Ultra-Low-Dropout Voltage Regulator for Precision Applications

In the realm of modern electronics, maintaining a stable and clean voltage supply is paramount for the reliable operation of sensitive circuits. The Infineon TLS805B1LDV50 stands out as a specialized solution, engineered to deliver exceptional performance in power-constrained and noise-sensitive environments. This ultra-low-dropout (LDO) voltage regulator provides a fixed output of 5.0V with a maximum output current of 50mA, making it an ideal choice for powering microcontrollers, sensors, and other critical low-power ICs.

A defining feature of this LDO is its ultra-low dropout voltage, which is typically a mere 85mV at a 50mA load. This exceptional characteristic allows the regulator to maintain a stable 5V output even when the input voltage dips very close to the output level, significantly enhancing system efficiency and extending operational life in battery-powered devices where every millivolt counts. Furthermore, it boasts an impressively low quiescent current of just 30µA (typical), which minimizes the device's own power consumption and is crucial for applications demanding high energy efficiency and longer battery life.

The TLS805B1LDV50 is designed with robustness and simplicity in mind. It requires only a small ceramic output capacitor for stability, simplifying board design and saving valuable space. Key protections such as internal current limiting and thermal shutdown are integrated to safeguard both the regulator and the load against fault conditions, enhancing the overall reliability of the end application. Its very small PG-TSON-2 package is perfect for space-constrained PCB designs.
