Microchip TC1185-3VCT713: A Compact Powerhouse for 3V Regulation

In the realm of modern electronics, stable and efficient voltage regulation is a cornerstone of reliable system performance. The Microchip TC1185-3VCT713 stands out as a premier solution, specifically engineered to deliver a fixed, precise 3.0V output from an input voltage range of 3.5V to 6.0V. This low-dropout (LDO) voltage regulator is designed to power a wide array of low-voltage microcontrollers, sensors, and portable devices with exceptional efficiency and minimal external components.

A defining feature of this regulator is its extremely low dropout voltage. At just 85mV typical at a 100mA load, the TC1185 can continue to regulate its output voltage even when the input voltage dips very close to the 3.0V output level. This characteristic is crucial for maximizing battery life in portable applications, allowing the system to operate until the battery is nearly depleted. Furthermore, the device boasts an impressively low ground current of just 85µA during full operation, which plummets to less than 1µA in shutdown mode. This ultra-low quiescent current makes it an ideal choice for battery-powered, always-on applications where every microamp of current consumption counts.

Beyond its power-saving credentials, the TC1185-3VCT713 offers robust performance features. It incorporates over-current and over-temperature protection circuits, safeguarding both the regulator itself and the sensitive load it powers from potential damage. The device is presented in a space-saving SOT-23-5 package, making it suitable for densely populated PCB designs. Its stability is ensured with any low-ESR ceramic output capacitor, simplifying the bill of materials and reducing overall design complexity. With a fast transient response, it effectively handles rapid changes in load current, maintaining a stable voltage rail for critical components.

ICGOOODFIND: The Microchip TC1185-3VCT713 is an exemplary LDO regulator that combines high efficiency, ultra-low power consumption, and robust protection in a miniature package. It is an optimal choice for designers seeking a reliable, compact, and energy-efficient power management solution for their 3V systems.
