概述

Description

The LM3480IM3-3.3 is a fixed output voltage linear voltage regulator from Texas Instruments. It is designed to provide a stable 3.3V output voltage with a maximum output current of 100 mA. The device features a low dropout voltage, making it suitable for applications where the input voltage is close to the output voltage. It typically comes in a SOT-23 package, which is compact and ideal for space-constrained applications.
Key features include:
1. Low Dropout Voltage: This ensures efficient operation even with small differences between input and output voltages.
2. Current Limiting: Protects the device from excessive current by limiting the output current.
3. Thermal Protection: Automatically shuts down the regulator if it exceeds a certain temperature, preventing damage from overheating.
4. Wide Input Voltage Range: Typically supports a range from 4.5V to 30V, allowing flexibility in power supply choices.
The LM3480IM3-3.3 is often used in portable devices, battery-powered equipment, and any application requiring a reliable 3.3V power supply with minimal external components.
