Overview

The MCP1700T-3302E/TT is a compact, low-dropout (LDO) linear voltage regulator designed for applications requiring stable power delivery with minimal quiescent current. It offers a fixed output voltage and is suitable for battery-powered devices due to its low power consumption. This regulator is available in a small SOT-23-3 package.

Why Choose This Part

Engineers choose the MCP1700T-3302E/TT for its ultra-low quiescent current of 1.6uA, which is critical for extending battery life in portable applications. Its small SOT-23-3 form factor and stable operation with a 1.0uF ceramic output capacitor simplify board layout. The integrated over current, over temperature, and short circuit protection features enhance system reliability.

Applications

Battery-Powered Devices
Its typical 1.6uA quiescent current makes it ideal for extending battery life in portable electronics, such as remote controls, sensors, and wearables.
Low-Power Microcontroller Supplies
