The MCP1700-4002E/TO from Microchip Technology is a highly efficient, low dropout (LDO) voltage regulator that offers excellent performance in a small form factor, making it ideal for portable electronic applications. This compact component is designed to provide a fixed output voltage of 4.0V with an input voltage range up to 6V, ensuring a stable power supply for your sensitive electronics.

Key Features

• Low Dropout Voltage: The MCP1700-4002E/TO maintains regulation with an extremely low dropout voltage of typically only 178mV at 250mA load, which enhances battery life in portable devices by allowing the battery to be drained further.
• High Output Current: This LDO is capable of delivering up to 250mA of output current, which is suitable for a wide range of applications, from microcontrollers to analog devices.
• Low Quiescent Current: The device features a low quiescent current of only 1.6 µA, which minimizes power consumption when in standby mode, further extending battery life in portable applications.
• Stable with Ceramic Output Capacitors: The MCP1700-4002E/TO is stable with ceramic output capacitors, offering a cost-effective solution without compromising performance. A minimum of 1µF capacitance with an X5R or better grade is recommended for stability.
• Thermal Overload Protection: The regulator includes an internal thermal overload protection that shuts down the output if the temperature exceeds the specified limits, protecting the device from damage due to overheating.
• Short-Circuit Protection: It also features short-circuit protection that helps safeguard the device and the load from potential damage caused by output short circuits.
