MCP1755ST-5002E/DB: A 500mA Low-Dropout Voltage Regulator Engineered for Performance and Efficiency

The MCP1755ST-5002E/DB is a high-performance, low-dropout (LDO) voltage regulator designed to deliver a stable 500mA output current with exceptional accuracy and efficiency. Optimized for power-sensitive applications, this regulator features an ultra-low dropout voltage of 178 mV at 500 mA, making it ideal for systems where input-to-output voltage differentials are minimal. Its fixed 5.0V output voltage ensures reliable power delivery for a wide range of electronic components, from microcontrollers to sensors.

Key advantages of the MCP1755 include its very low quiescent current (typically 16 µA), which significantly reduces power dissipation in standby or idle modes. This trait is critical for battery-powered devices, extending operational life and enhancing energy efficiency. The device also incorporates advanced protection features such as overcurrent protection (OCP) and thermal shutdown, safeguarding both the regulator and the downstream circuitry under fault conditions.

Housed in a space-efficient SOT-223 package, the MCP1755ST-5002E/DB offers excellent thermal performance and is well-suited for compact PCB designs. Its stable operation with low-ESR ceramic capacitors further simplifies design-in and reduces overall system cost.

ICGOODFIND: The MCP1755ST-5002E/DB stands out as a robust, high-efficiency LDO solution for applications demanding precise voltage regulation and extended battery life, including IoT devices, portable electronics, and embedded systems.
