Overview
The LM29150R-5.0 is a fixed-output low-dropout voltage regulator from the TAEJIN LM2915x series, providing a guaranteed 5.0V output with ±1% initial tolerance at 25°C. It supports up to 1.5A load current with a typical dropout voltage of 350mV at full load and features very low ground current. The device operates within an input voltage range of 2.3V to 26V and includes internal protections against overcurrent, thermal overload, and reverse polarity.
Feature Summary
- High current capability of 1.5A with extremely fast transient response
- Low dropout voltage performance using PNP pass element technology
- Comprehensive protection including current limiting, thermal shutdown, and reverse-battery/load dump protection
- Moisture sensitivity level 3 compliance for robust assembly
Applications
- Battery powered equipment
- High-efficiency linear power supplies
- Post-regulator for switching supplies
- Automotive electronics
Procurement Notes
Verify the specific suffix 'R' corresponds to the TO-263 package configuration as defined in the ordering information table. Confirm that the '5.0' designation matches the required fixed output voltage. Ensure compatibility with the manufacturer's active status and revision history before finalizing procurement specifications.
Selection Notes
Select this component when a stable 5.0V rail is required under high load conditions with minimal input-to-output voltage differential. The TO-263 package offers suitable thermal dissipation characteristics for moderate power applications. Consider the ±1% accuracy specification for precision requirements and ensure adequate heat sinking based on calculated power dissipation.
Part Context
This part belongs to the LM2915x family, which includes LM29150 (fixed), LM29151 (fixed with enable), and LM29152 (adjustable). The 'R' suffix indicates the TO-263 surface-mount package variant. The series utilizes a PNP pass element process to achieve superior dropout performance compared to traditional NPN designs.

FAQ
What is the minimum operating input voltage for the LM29150R-5.0?
The minimum operating input voltage is determined by the sum of the nominal output voltage plus the dropout voltage, or 2.3V, whichever is greater.
Does the LM29150R-5.0 include an enable pin?
No, the LM29150 version does not feature an enable pin; only the LM29151 and LM29152 versions include logic-controlled electronic shutdown capabilities.
