Overview
The LM29150RS-12 is a fixed-output low-dropout voltage regulator manufactured by TAEJIN (HTC Korea). It provides a guaranteed 1.5A output current with a typical dropout voltage of 350mV at full load. The device features a TO-252 package and delivers a precise 12V output with an initial tolerance of ±1%. It incorporates internal protections including current limiting, thermal shutdown, and reverse polarity protection.
Feature Summary
- High current capability up to 1.5A with very low dropout voltage
- Accurate 1% guaranteed initial output voltage tolerance
- Integrated reverse-battery and load dump protection
- Zero-current shutdown mode for minimal power consumption
Applications
- Battery powered equipment
- Automotive electronics
- High-efficiency linear power supplies
- Post-regulator for switching supplies
Procurement Notes
Verify the specific suffix RS indicates the TO-252 surface-mount package configuration. Confirm the '12' designation corresponds to the fixed 12V output variant. Ensure compatibility with the manufacturer's latest revision 1.6.3 datasheet specifications regarding absolute maximum ratings and thermal resistance values before finalizing procurement orders.
Selection Notes
Select this component when a stable 12V rail is required under high load conditions. The PNP pass element design ensures superior dropout performance compared to older NPN designs. Consider the TO-252 package for space-constrained PCB layouts requiring efficient heat dissipation through the tab.
Part Context
This part belongs to the LM2915x series, which includes LM29150 (fixed), LM29151 (fixed with enable), and LM29152 (adjustable). The RS suffix specifically denotes the TO-252 package format within HTC Korea's lineup of high-performance low-dropout regulators designed for moderate to high current applications.

FAQ
What is the minimum input voltage required for proper regulation?
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 this specific model include an enable pin?
No, the LM29150 is the base fixed version without logic control. The LM29151 variant includes the enable pin feature.
