LM1117MP-3.3/NOPB
Overview
The LM1117MP-3.3/NOPB is a low-dropout linear regulator capable of providing up to 800mA of output current at a fixed 3.3V. It is a popular power management solution for providing local regulation in digital systems, industrial modules, and server power supplies. The device includes integrated current limiting and thermal protection to ensure circuit reliability during fault conditions.
Why Choose This Part
The LM1117 series offers a robust 800mA output capacity in a compact SOT-223 package, making it suitable for space-constrained designs requiring moderate current. It features internal thermal overload protection and current limiting to prevent damage during short circuits or overheating.
Applications
Key Specifications
Getting Started
When designing with the LM1117MP-3.3/NOPB, ensure a minimum of 10uF tantalum capacitor is placed on the output to maintain stability and improve transient response. Designers should calculate the power dissipation (Vin - Vout) * Iout to ensure the SOT-223 package does not exceed the 125C maximum junction temperature.
