Microchip Technology MCP1790T-3302E/EB High-Voltage Regulator

The MCP1790T-3302E/EB from Microchip Technology is a high-performance, high-voltage regulator designed to provide excellent power management solutions for automotive, industrial, and robust electronic applications. This device is capable of handling input voltages up to 45V, making it an ideal choice for systems that experience large voltage transients, such as those found in automotive environments.

With a fixed output voltage of 3.3V, the MCP1790T-3302E/EB can deliver up to 70mA of continuous current. This makes it suitable for powering microcontrollers, sensors, and other low-power devices that require a stable voltage supply. The low dropout voltage ensures efficient operation even when the input voltage is close to the output voltage, thereby minimizing power losses and improving overall system reliability.

The device features a low quiescent current, which is particularly beneficial for battery-powered applications where extending the battery life is critical. Additionally, the MCP1790T-3302E/EB is equipped with thermal shutdown and short-circuit protection, enhancing the safety and durability of the end application by preventing damage due to overheating or fault conditions.

For design flexibility, this regulator comes in a thermally efficient 3-pin TO-220 package, which not only simplifies the PCB layout but also aids in heat dissipation. Its extended temperature range from -40°C to +125°C guarantees stable performance across a wide range of operating conditions, making it a versatile choice for harsh environments.
