Microchip TC2117-3VDBTR: Powering Modern Portable Electronics with High Efficiency

In the rapidly evolving world of portable and battery-powered devices, power management is paramount. The Microchip TC2117-3VDBTR stands out as a critical component, a 150 mA low-dropout (LDO) linear voltage regulator engineered specifically for applications where efficiency, size, and longevity are non-negotiable. This device delivers a fixed 3.3V output from an input range of 2.7V to 6.0V, making it exceptionally versatile for a wide array of modern electronics.

A defining characteristic of the TC2117 is its remarkably low quiescent current. Typically drawing just 19 µA under load and a mere 0.1 µA when disabled, this LDO is a perfect fit for devices that spend significant time in sleep or standby modes. This ultra-low current consumption directly translates to extended battery life, a crucial selling point for products like IoT sensors, wearable health monitors, and other always-on, power-sensitive applications.

Beyond its efficiency, the TC2117 is designed for robustness and stability. It features very low dropout voltage, ensuring stable operation even as the input voltage dips close to the output level, thereby maximizing the usable energy from a battery. The regulator maintains a stable output with a very small 1.0 µF ceramic capacitor, reducing both the solution size and bill-of-materials cost. Furthermore, built-in protections such as current limit and thermal shutdown safeguard the device and the downstream circuitry from potential damage during fault conditions.

Housed in a space-saving SOT-23-5 package, the TC2117-3VDBTR offers a high-performance power management solution with an absolute minimal footprint. Its combination of low noise, fast transient response, and high power supply rejection ratio (PSRR) also makes it suitable for powering noise-sensitive analog and RF components.

ICGOODFIND: The Microchip TC2117-3VDBTR is an exemplary LDO regulator that masterfully balances performance with power conservation. Its ultra-low quiescent current, stable operation with minimal external components, and integrated protection features make it an superior choice for designers aiming to create smaller, smarter, and longer-lasting portable electronic devices.
