SPX29150T-L-5-0/TR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The SPX29150T-L-5.0/TR is a fixed-output low-dropout voltage regulator manufactured by Diodes Incorporated, formerly Sipex. It provides a stable 5.0V output with a maximum load current of 1.5A. The device features a typical dropout voltage of 390mV at full load and maintains 1% initial output accuracy. Designed for high-current applications, it includes internal over-current and thermal protection mechanisms to ensure reliable operation in demanding power supply environments.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the manufacturer origin, as this component was originally produced by Sipex Corporation before acquisition by Exar and subsequently Diodes Incorporated. Confirm that the specific suffix indicates the standard tape-and-reel packaging format. Ensure the part number matches the required 5.0V fixed output variant rather than adjustable or other voltage options within the series.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this regulator when a fixed 5.0V rail is required with high current capacity up to 1.5A. It is suitable for designs needing tight line and load regulation without external feedback components. Consider the thermal performance in the TO-263 package if operating near maximum current limits. Verify input voltage headroom against the 390mV typical dropout specification to maintain regulation under all load conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This component belongs to the SPX29150 series of high-current low-dropout regulators. The series offers both fixed and adjustable output versions, sharing common architectural features such as Superßeta PNP processing technology. This specific model represents the fixed 5.0V variant designed for general-purpose high-efficiency power distribution in computer and multimedia systems.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Compatible replacements include MIC29150 from Microchip and LD29150 from STMicroelectronics. These devices share similar 1.5A current ratings and low-dropout characteristics. Verify pin compatibility and thermal resistance values before substitution.
