MCP1702T-2502E/MB 250mA Low-Dropout (LDO) Voltage Regulator Technical Overview
The MCP1702T-2502E/MB is a compact, high-performance low-dropout voltage regulator from Microchip Technology, designed to deliver a fixed 2.5V output at up to 250mA of continuous current. Optimized for battery-powered and low-power applications, this LDO combines high efficiency with a very low quiescent current, making it an ideal choice for portable and always-on devices.
A key feature of the MCP1702 is its remarkably low dropout voltage—typically 178mV at 250mA load—allowing it to maintain stable output even when the input voltage is very close to the output level. This is particularly advantageous in battery-operated systems where maximizing usable battery life is critical. Furthermore, the device boasts an extremely low quiescent current of just 2.0µA (typical), which minimizes power loss and significantly extends battery runtime in standby or sleep modes.
The regulator is designed for stability with small, space-saving ceramic output capacitors as low as 1.0µF, reducing both the solution size and bill-of-materials cost. It incorporates essential protection features such as current limit and thermal shutdown, safeguarding both the IC and the downstream circuitry from fault conditions.
Housed in a SOT-23-3 package, the MCP1702T-2502E/MB offers a miniature footprint for densely populated PCBs. Its combination of low noise, high power supply rejection ratio (PSRR), and robust performance makes it a versatile solution for powering microcontrollers, sensors, and other critical components in applications like IoT nodes, smart watches, and consumer electronics.
ICGOODFIND: The MCP1702T-2502E/MB stands out as an exceptional LDO for power-sensitive designs, offering an optimal blend of ultra-low quiescent current, low dropout voltage, and miniature packaging to enable efficient and reliable power management.
