Microchip Technology, Inc. Ic, Ldo Volt Reg, 3.3V, 0.3A, Sot223-3; Output Type Microchip MCP1755ST-3302E/DB

The MCP1755S is a low-dropout (LDO) voltage regulator designed to provide a fixed output voltage of 3.3V with a maximum output current of 300mA. It operates within an input voltage range of 3.6V to 16V, making it suitable for various battery-powered applications. The typical quiescent current is low at 68.0¬µA, which enhances efficiency in portable devices. This LDO features a low dropout voltage of 300mV at full load, ensuring stable performance even with minimal input-output voltage differential. The output voltage tolerance is ¬±2.0% across the specified temperature range of -40¬8C to +125¬8C, providing reliable voltage regulation. The device is stable with a minimum output capacitance of 1¬µF, allowing for flexibility in capacitor selection. Additional protective features include overcurrent limit, overtemperature shutdown, and true current foldback, which enhances the robustness of the device in various operating conditions. The MCP1755S is packaged in a compact SOT-223-3 format, making it suitable for space-constrained applications.
