What brands and models can LD1117AG-5.0V-A SOT-223 replace

LD1117AG-5.0V-A SOT-223 is a low dropout linear regulator (LDO) with stable performance and wide applications. When replacing similar products from other brands, key factors such as output voltage, output current, packaging form, and work efficiency need to be considered. Here are some possible alternative brands and their models:

1、 Alternative brands and models
AMS（Advanced Monolithic Systems）
model: AMS1117-5.0
Explanation: The AM11117 series is a classic linear regulator launched by AMS company. The output voltage of AM1117-5.0 is 5.0V, which is the same as the output voltage of LD1117AG-5.0V-A. Meanwhile, AM11117 is often packaged in SOT-223 and other forms, making it a viable alternative to LD1117AG-5.0V-A in certain applications.
Texas Instruments (TI)
model: TLV1117-5.0
Explanation: The TLV1117 series is a low dropout linear regulator launched by Texas Instruments, featuring high performance and low power consumption. The output voltage of TLV1117-5.0 is also 5.0V, and the packaging form is mostly SOT-223, so it can also be used as a substitute for LD1117AG-5.0V-A.
On Semiconductor
model: NCP1117-5.0
Explanation: NCP1117 series is a linear regulator launched by Anson Mei, which has excellent stability and reliability. The output voltage of NCP1117-5.0 is 5.0V, and its packaging form is similar to LD1117AG-5.0V-A, so it can also be used as a substitute.
Microdiode Electronics
model: ME1117-5.0
Explanation: ME1117 series is a linear regulator launched by Weimeng Electronics, which has stable performance and moderate price. The output voltage of ME1117-5.0 is 5.0V, suitable for various electronic devices that require a stable 5V power supply. Although the packaging form may vary depending on different batches or manufacturers, it can also serve as a substitute for LD1117AG-5.0V-A in certain applications.
2、 Alternative precautions
Packaging form: Although the packaging form of the above alternatives is mostly SOT-223, it is still necessary to confirm whether the packaging is completely matched in specific applications to ensure the feasibility and reliability of installation.
Electrical characteristics: When replacing, it is necessary to carefully compare the electrical characteristics of the substitute, such as output voltage accuracy, maximum output current, operating temperature range, etc., to ensure that the substitute can meet the requirements of the original application.
Price and Supply: Different brands and models of voltage regulators may have differences in price and supply. When choosing alternatives, it is necessary to comprehensively consider factors such as price, supply stability, and the manufacturer's reputation.
In summary, LD1117AG-5.0V-A SOT-223 can replace linear regulators from brands and models such as AMS' AM1117-5.0, Texas Instruments' TLV1117-5.0, ON Semiconductor 'NCP1117-5.0, and Weimeng Electronics' ME1117-5.0. When replacing, it is necessary to carefully compare factors such as packaging form, electrical characteristics, price, and supply to ensure the applicability and reliability of the substitute.
