Overview
The LM29150R-3.0 is a fixed-output low-dropout voltage regulator manufactured by TAEJIN (HTC Korea). It provides a guaranteed 3.0V output with ±1% initial tolerance and supports up to 1.5A load current. The device features a typical dropout voltage of 350mV at full load and very low ground current. It is housed in the TO-263 package and includes internal protections against overcurrent, thermal overload, and reverse polarity.
Feature Summary
- High current capability supporting loads up to 1.5A
- Low dropout voltage performance for efficient power regulation
- Accurate 1% guaranteed initial output voltage tolerance
- Integrated reverse-battery and load dump protection
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 manufacturer's ordering information. Confirm that the 3.0V fixed output variant matches the required system voltage. Ensure compatibility with the intended thermal management strategy given the junction-to-case resistance specifications.
Selection Notes
Select this component when a stable 3.0V rail is required under high current conditions. The PNP pass element design offers superior dropout characteristics compared to older NPN designs. Consider the TO-263 package for applications requiring moderate heat dissipation capabilities without the bulk of larger through-hole packages.
Part Context
This part belongs to the LM2915x series, which includes fixed voltage (LM29150), logic-enabled versions (LM29151), and adjustable versions (LM29152). The family utilizes a PNP pass element process to achieve low dropout voltages and high accuracy across a wide range of operating temperatures and load conditions.
Replacement Considerations
Compatible substitutes within the same family include LM29150T-3.0 (TO-220) and LM29150RS-3.0 (TO-252). Cross-manufacturer equivalents such as LD29150 or SPX29150 may offer similar electrical profiles but require verification of pinout and thermal parameters.
