The Microchip TC1223-4.0VCTTR is a high-accuracy, low-dropout (LDO) linear voltage regulator designed for battery-operated systems. It provides a fixed 4V output voltage with a maximum output current of 50mA.
Key features include extremely low ground current, typically 50µA at full load, which significantly extends battery life compared to bipolar regulators. It also offers a very low dropout voltage, typically 85mV at 50mA, and a power-saving shutdown mode that reduces supply current to a maximum of 0.5µA.
This device incorporates over-current and over-temperature protection for enhanced reliability. It is stable with a small output capacitor of 1µF. The regulator is housed in a space-saving 5-pin SOT-23A package, making it suitable for compact designs.
Applications include battery-powered devices, portable computers, medical instruments, and instrumentation. It serves as a pin-compatible upgrade for older bipolar regulators.
