REG71055DDCT - Texas Instruments

The REG71055DDCT is a highly efficient, versatile voltage regulator designed by Texas Instruments, a leader in semiconductor solutions. This compact device is part of the REG710 family, known for its low-power operation and ability to maintain stability with low-value output capacitors, making it perfect for space-constrained applications.

This step-up DC-DC converter operates at a fixed frequency of 1 MHz, which allows for the use of small surface-mount inductors and capacitors. Despite its small size, the REG71055DDCT boasts a 5.5V maximum input voltage and a fixed 5V output, with an impressive output current up to 60 mA. The high switching frequency paired with its high-efficiency performance, typically up to 96%, ensures minimal power loss during operation, making it ideal for battery-powered devices.

The REG71055DDCT comes in a 6-pin SOT-23 package, which is favored for its minimal footprint on PCBs. It incorporates a host of features to safeguard your application, including thermal overload protection, under-voltage lockout, and a shutdown mode that reduces the quiescent current to less than 1 µA, further prolonging battery life.

With its wide operating temperature range of -40°C to 85°C, the REG71055DDCT can reliably perform in various environments, from industrial to commercial. This makes the device an excellent choice for portable electronics, small handheld devices, and other applications where space and power efficiency are critical.

Overall, the REG71055DDCT stands out for its combination of high efficiency, small size, and robust protection features. Whether you're developing a new portable gadget or looking to improve the power management in your current application, the REG71055DDCT from Texas Instruments is a component that promises to deliver reliable performance in a tiny package.
