LM1117T3.3 Description

Short technical summary and product information.

The Texas Instruments LM1117T3.3 is a compact, low dropout linear voltage regulator designed for applications requiring up to 800mA of output current. This specific model provides a stable 3.3V output voltage, making it suitable for a wide range of electronic circuits.

 

Key electrical characteristics include a maximum input voltage of 15V and a typical dropout voltage of 1.2V at 800mA load. The regulator offers good line regulation (0.2% max) and load regulation (0.4% max). It also incorporates internal current limiting and thermal shutdown features for protection.

 

The LM1117T3.3 is housed in a TO-220 package, designed for through-hole mounting. This package type is common in power supply designs and offers adequate thermal dissipation. The operating temperature range is specified from 0°C to 125°C.

 

This device is a reliable choice for power management in various electronic systems where a regulated, low-voltage DC supply is needed. Its fixed output voltage simplifies design and reduces component count compared to adjustable regulators.
