LM1117IDTX in LM1117 / LD1117 LDO Family
The LM1117IDTX family, primarily manufactured by Texas Instruments, consists of low-dropout linear regulators capable of providing up to 800mA of output current. This sub-family is characterized by its TO-252 (DPAK) packaging, which offers a balance between compact surface-mount footprint and effective thermal dissipation. These devices are essential for post-regulation of switching power supplies and local on-card regulation, providing stable fixed or adjustable voltage rails for digital and analog circuitry in industrial and consumer electronics.
Variants in This Sub-Family
Variants within the LM1117IDTX sub-family primarily differ by their output voltage configuration and environmental compliance. Options include fixed output voltages such as 1.8V, 2.5V, 3.3V, and 5.0V, as well as an adjustable version that utilizes an external resistor divider. The /NOPB suffix indicates Lead-Free (No Pb) packaging, complying with RoHS standards, which is critical for modern industrial manufacturing requirements.
