LM1117T-3.3/NOPB

Overview

The LM1117T-3.3/NOPB is a fixed-output low-dropout linear regulator manufactured by Texas Instruments, providing a stable 3.3 V output with a maximum load current of 800 mA. It operates within an input voltage range up to 15 V and features a typical dropout voltage of 1.2 V at full load. The device incorporates internal current limiting and thermal shutdown protection mechanisms. It utilizes a Zener-trimmed bandgap reference to ensure output voltage accuracy within ±1%. The component is housed in a TO-220 package and is designed for operation across a temperature range from 0°C to +125°C.

Feature Summary

Provides a fixed 3.3 V output regulated by an internal Zener-trimmed bandgap reference.
Includes integrated current limiting and thermal shutdown circuitry for robust protection.
Delivers high ripple rejection performance suitable for noise-sensitive applications.

Applications

AC drive power stage modules
Merchant network and server PSU
Industrial AC/DC power supplies
Ultrasound scanners
Servo drive control modules

Procurement Notes

Verify the specific suffix 'T' corresponds to the TO-220 package configuration as defined in the manufacturer's orderable addendum. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance status according to the latest datasheet revision. Ensure the operating environment remains within the specified 0°C to +125°C junction temperature limits to maintain guaranteed electrical characteristics.

Selection Notes

Select this component when a fixed 3.3 V rail is required with up to 800 mA capacity. The TO-220 package offers superior thermal dissipation compared to surface-mount options, making it suitable for higher power dissipation scenarios. Consider the minimum dropout voltage requirements relative to the input supply voltage to ensure regulation is maintained under all load conditions.

Part Context

This part belongs to the LM1117 family of 800 mA low-dropout linear regulators. The family includes adjustable versions and other fixed voltages such as 1.8 V, 2.5 V, and 5.0 V. The LM1117 serves as a legacy alternative to newer devices like the TLV1117 and TLV761, which offer improved functionality or drop-in compatibility in different package configurations.
