MCP1826T-2502E/DC 250mA Low-Dropout Voltage Regulator Technical Overview

The MCP1826T-2502E/DC is a high-performance, low-dropout (LDO) voltage regulator from Microchip Technology, designed to deliver a fixed 2.5V output with a maximum output current of 250mA. It is engineered for applications requiring a stable, clean voltage supply from a slightly higher input source, even when the input voltage is very close to the output level.

A key feature of this LDO is its extremely low dropout voltage—typically 120 mV at 250 mA—which enables it to maintain regulation even as the input voltage dips nearly to the output level. This characteristic is crucial for power-sensitive designs, especially in battery-powered applications where maximizing run-time is essential. Furthermore, the device boasts a low quiescent current of just 120 µA (typical), which helps conserve power when the system is in a standby or low-power mode.

The MCP1826T-2502E/DC is also designed for stability and reliability. It requires only a small, space-saving 1.0 µF ceramic output capacitor for stable operation, making it an excellent choice for compact printed circuit boards (PCBs). The regulator includes vital protection features such as current limit and thermal shutdown, safeguarding both the IC and the system it powers from damage under fault conditions.

Housed in a SOT-23-5 package, this LDO offers a great combination of performance and small physical size, suitable for a wide range of consumer and industrial electronics, including portable devices, smart sensors, and battery-powered equipment.

ICGOOODFIND: The MCP1826T-2502E/DC stands out as an efficient and robust power management solution, offering excellent line and load regulation, very low dropout, and critical protection features in a miniature package, making it ideal for space-constrained and power-conscious designs.
