MCHPMCP1700T-1802E/TT
Overview
The Microchip MCP1700T-1802E/TT is a low-cost, low-dropout (LDO) linear regulator providing a fixed 1.8V output with a maximum output current of 200mA. It is designed for simple, low-current power domains and features a very low quiescent current, making it suitable for battery-powered applications. The device is stable with a 1.0 uF ceramic output capacitor.
Why Choose This Part
Engineers benefit from its very low quiescent current, which is critical for extending battery life in portable and IoT applications. Its small SOT-23 package minimizes PCB footprint, and it includes essential protection features like overcurrent and overtemperature shutdown. The ability to use a small 1.0 uF ceramic output capacitor simplifies BOM and reduces board space.
Applications
Key Specifications
Getting Started
This LDO is a fundamental component for power management. Design involves selecting appropriate input and output capacitors (e.g., 1.0 uF ceramic output capacitor for stability) and ensuring the thermal design can dissipate power if operating near maximum current. Standard PCB layout practices for power components should be followed to minimize noise and improve performance.
