MICROCHIP TC1015 3.3V LDO Voltage Regulator, 100mA, SOT-23-5

The MICROCHIP TC1015-3.3VCT713 is a high-accuracy, fixed-output Low Dropout (LDO) voltage regulator designed for precision power management in space-constrained, battery-operated devices. Built with CMOS technology, it eliminates wasted ground current, significantly extending battery life with a total supply current of just 50µA at full load—up to 60 times lower than traditional bipolar regulators.

This regulator features a very low dropout voltage of typically 180mV at full load (100mA), ensuring stable 3.3V output even as input voltage approaches the output level, maximising energy efficiency. It offers high output voltage accuracy, typically within ±0.5%, which is crucial for sensitive electronic circuits.

Key operational features include a power-saving shutdown mode that reduces supply current to a maximum of 0.5µA and allows the output voltage to fall to zero. A reference bypass input is provided for ultralow-noise operation, making it ideal for noise-sensitive applications like sensing and instrumentation. The device is fully protected with both overcurrent and over-temperature safeguards.

Housed in a compact SOT-23-5 surface-mount package, it is a pin-compatible upgrade for older bipolar regulators, offering a straightforward path to improved performance and efficiency. Its wide operating temperature range from -40°C to 125°C ensures reliability in demanding environments.
