MCP1702T-5002E/MB: Microchip’s 500mA Low-Dropout Voltage Regulator for Modern Electronics

In the world of power management, efficiency and reliability are paramount. The MCP1702T-5002E/MB from Microchip Technology stands out as a robust 500mA low-dropout (LDO) voltage regulator designed to meet the demanding requirements of today’s compact and power-sensitive applications. With its fixed 5.0V output, this LDO provides a stable and clean voltage supply, making it an ideal choice for a wide range of electronic devices.

One of the key features of the MCP1702T-5002E/MB is its extremely low dropout voltage—typically 178mV at 500mA load—ensuring efficient operation even when the input voltage is very close to the output level. This characteristic is crucial for battery-powered applications, such as IoT nodes, portable medical devices, and handheld instruments, where maximizing battery life is essential. The device operates with a very low quiescent current of just 2.0µA, further enhancing energy efficiency and extending operational time in standby modes.

Beyond efficiency, the MCP1702T-5002E/MB offers excellent performance in terms of stability and simplicity. It requires only a small 1.0µF ceramic output capacitor for stable operation, reducing both board space and component cost. The LDO also includes built-in protection features such as current limit and thermal shutdown, safeguarding the regulator and the downstream circuitry under fault conditions. With an input voltage range from 2.7V to 13.2V, it accommodates various power sources, including lithium-ion batteries and regulated DC supplies.

Housed in a compact SOT-89-3 package, this regulator is suited for space-constrained designs. Its low noise output makes it particularly valuable for powering analog sensors, microcontrollers, and RF modules, where voltage ripples could impair performance. Whether used in consumer electronics, industrial systems, or automotive applications, the MCP1702T-5002E/MB delivers dependable power with minimal overhead.
