The Microchip TC1017-8VCTTR: Precision Power in a Miniature Package

In the realm of modern electronics, efficient and reliable voltage regulation is a cornerstone of stable system performance. The Microchip TC1017-8VCTTR stands out as a premier solution, engineered to deliver clean, stable power for a vast array of portable and space-constrained applications. This 150 mA low-dropout (LDO) linear voltage regulator combines high performance with an exceptionally small footprint, making it an ideal choice for designers prioritizing both size and power quality.

A defining characteristic of the TC1017 is its extremely low dropout voltage. With a typical dropout of just 80 mV at 50 mA load, the regulator can maintain a stable output even when the input voltage dips very close to the output level. This capability is crucial for maximizing battery life in portable devices, allowing them to operate effectively until the battery is nearly depleted. Furthermore, the device boasts very low ground current, which remains stable across variations in load, input voltage, and temperature. This translates directly to higher efficiency and longer operational times for battery-powered products.

Beyond its core regulation function, the TC1017 is designed for exceptional stability and simplicity. It requires only a small, space-saving 1.0 µF ceramic capacitor on the output, eliminating the need for expensive or bulky components. Its design ensures stability over the entire range of output currents and temperatures. The regulator also features internal current limiting and thermal shutdown protection, safeguarding both the IC and the downstream circuitry under fault conditions.

Housed in a minuscule 5-pin SOT-23 package, the TC1017-8VCTTR provides a fixed 1.8V output, offering a perfect power solution for low-voltage microcontrollers, sensors, and wireless communication modules. Its combination of miniature size, low quiescent current, and high PSRR (Power Supply Rejection Ratio) makes it indispensable for noise-sensitive applications like medical devices, IoT sensors, and handheld instruments.

ICGOODFIND: The Microchip TC1017-8VCTTR is a highly efficient, miniature LDO regulator that excels in providing stable, clean power for battery-dependent and space-sensitive designs. Its ultra-low dropout voltage and ground current are key features that empower engineers to create more efficient and longer-lasting portable electronic products.
