MCHPTC1262-3.3VDBTR
Overview
The TC1262-3.3VDBTR is a fixed 3.3V linear voltage regulator from Microchip Technology capable of delivering up to 500mA of output current. It is AEC-Q100 automotive qualified and features a low typical quiescent current of 80uA, making it suitable for battery-powered and automotive applications. The device is housed in a SOT-223 package designed for efficient thermal dissipation while maintaining a small surface-mount footprint.
Why Choose This Part
The regulator offers a high PSRR of 64dB at 1kHz and a fast response to step changes in load, ensuring stable power delivery. Its AEC-Q100 qualification and wide operating temperature range of -40C to 125C provide high reliability in harsh environments. Integrated protection features like thermal shutdown and overcurrent limiting simplify circuit design by removing the need for external protection components.
Applications
Key Specifications
Getting Started
When designing with the TC1262, ensure a minimum 1uF ceramic or tantalum capacitor is placed at the output for stability. The SOT-223 package utilizes the center pin (Pin 2) and the large tab for heat dissipation, so provide adequate copper area on the PCB for thermal management. Refer to the Microchip datasheet for specific ESR requirements of the output capacitor to prevent oscillation.
