TI LDO Regulators

Key Features

• 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

Packages, Temperature & Applications

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.

Selection Notes

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.

Popular Part Numbers

• LM1117MP-3.3 — 800 mA fixed 3.3 V in SOT-223.
• LM2940CT-5.0 — 1 A fixed 5 V in TO-220.
• LM317T — 1.5 A adjustable 1.25 V to 37 V.
• TPS7A3301RGWR — low-noise negative LDO.
• TLV75733PDBVR — 1 A fixed 3.3 V in SOT-23.

Design Considerations

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.

Why Choose This Series

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.

How to Order

To request a quote, open any part number below and use the RFQ form with your target quantity, target price and country. We confirm availability, lead time and date code before you commit, and provide batch and date-code traceability on request.

Sourcing & Quality

CHIPER sources brand-new, unused components and provides quality inspection, batch and date-code traceability, shortage and long lead-time sourcing, and one-stop BOM procurement. Every part is verified before shipment, and availability, lead time and date code are confirmed at the time of quotation.
