MCP1700T-2502E/MB linear voltage regulators are designed to provide low-noise, low-dropout voltage regulation for smaller applications. The MCP1700T-2502E/MB is a low-side linear regulator that delivers up to 250mV of dropout voltage at 2A of output current. The MCP1700T-2502E/MB can operate with input voltage of up to 21V, and provides a very low-noise output at the same time. Application The MCP1700T-2502E/MB is well suited for applications where low-noise, low-dropout voltage regulation is required, such as portable computers, audio systems, and calibration/system monitoring systems. It is also often used as a post-regulation filter in systems where the high quality of power supply regulation is necessary or when faster transient response is desired.Working PrincipleThe MCP1700T-2502E/MB is a low-side linear voltage regulator. It operates by maintaining a fixed difference in its input and output voltage. It accomplishes this by driving current directly into the output terminal. The input voltage of the regulator is set by an external resistor divider, with the output voltage following accordingly. The MCP1700T-2502E/MB uses a biasing circuit to ensure smooth, consistent operation even when the output voltage drops close to the input voltage. The biasing circuit activates at a certain differential voltage, providing additional current to the output terminal to ensure that the output voltage doesn\'t collapse.The MCP1700T-2502E/MB also includes a thermal shut-off circuit that protects the device from high temperature damage. The thermal shut-off circuit will shut down the regulator if the die temperature exceeds a certain threshold. The MCP1700T-2502E/MB can be powered with either an AC or DC input voltage. It has an internal current limiter to protect it from an overcurrent condition, and an internal current leak to maintain stability. It also has an enable shut-down pin, allowing the user to remotely shut down the regulator if needed.In summary, the MCP1700T-2502E/MB is a low-noise, low-dropout linear voltage regulator designed to provide clean, stable power with a wide input voltage range and a low dropout voltage. It is well suited for portable and audio applications, as well as any system where the quality of the power supply regulation is critical.
