TI LDO Regulators
\n\n
Texas Instruments low-dropout regulators provide clean, low-noise voltage rails from a slightly higher input. From classic LM1117 and LM317 parts to modern low-noise TPS7A and TLV7xx families, TI LDOs cover fixed and adjustable outputs for analog and digital circuits.
\n\n
Key Features
\n
- Fixed and adjustable output voltages
- Output current from 100 mA to 4 A
- Low dropout and high PSRR for clean rails
- Low-noise families for RF and analog supplies
- SOT-23, SOT-223, TO-220, TO-252 and VQFN packages
- Commercial and industrial temperature grades
\n\n
Packages, Temperature & Applications
\n
TI LDOs are supplied in SOT-23, SOT-223, TO-220, TO-252, VQFN and MSOP packages, across commercial and industrial temperature ranges. Applications include point-of-load regulation, low-noise analog and RF supplies, battery-powered devices and industrial power rails.
\n\n
Selection Notes
\n
Match the output voltage and current to your rail, then check dropout and noise. Fixed-output parts need no resistors, while adjustable parts give any rail. Low-noise, high-PSRR families keep sensitive analog and RF supplies clean. Confirm package and temperature grade by RFQ.

Design Considerations
\n
Match the output voltage and current to your rail, then check dropout and noise. Fixed-output parts need no external resistors, while adjustable parts give any rail from one part number. Low-noise, high-PSRR families keep sensitive analog and RF supplies clean, and the package and temperature grade should match your board and environment.
\n\n
Why Choose This Series
\n
TI LDOs combine wide availability, consistent quality and detailed documentation with a broad range of package, current and noise options. Whether the design needs a simple 100 mA rail or a low-noise 4 A supply for an FPGA, the TI portfolio has a matching part with predictable dropout, PSRR and thermal behaviour, backed by long product lifecycles.
