Overview
The LM29150R-12 is a fixed-output low-dropout voltage regulator manufactured by TAEJIN (HTC Korea). It provides a guaranteed 1.5 A output current with a typical dropout voltage of 350 mV at full load. The device features an accurate initial tolerance of ±1% and utilizes a PNP pass element for high efficiency. It operates within an input voltage range up to 26 V and supports junction temperatures from -40 °C to +125 °C. The component is housed in a TO-263 package.
Feature Summary
- High current capability of 1.5 A with very low dropout voltage
- Accurate 1% guaranteed initial output voltage tolerance
- Integrated reverse-battery and load dump protection
- Zero-current shutdown mode available in the 5-pin version
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 surface-mount package configuration. Confirm that the ordering code matches the required 12 V fixed output variant. Ensure compatibility with the intended thermal management strategy, as the device dissipates significant heat at high currents. Check for any specific moisture sensitivity level requirements during assembly.
Selection Notes
Select this component when a stable 12 V rail is required under heavy loads up to 1.5 A. The low dropout characteristic makes it suitable for systems where the input voltage is close to the desired output. Consider the TO-263 package for surface-mount applications requiring efficient heat dissipation. Verify that the application does not exceed the maximum operating input voltage of 26 V.
Part Context
This part belongs to the LM2915x series of high-performance low-dropout regulators. The family includes variants like LM29150 (fixed), LM29151 (fixed with enable), and LM29152 (adjustable). The 'R' suffix indicates the TO-263 package type, distinguishing it from TO-220 or TO-252 options. These regulators are designed for moderate to high current applications requiring high accuracy and robust protection features.

FAQ
What is the maximum operating input voltage?
The recommended operating input voltage is up to 26 V, although the absolute maximum rating allows brief exposure to 60 V.
Does the LM29150R-12 include an enable pin?
No, the LM29150 is a 3-pin fixed regulator without an enable pin. The LM29151 variant includes an enable pin.
How is the dropout voltage defined?
Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its nominal value.
