Overview
The LM29150RS-5.0 is a fixed-output low-dropout voltage regulator manufactured by TAEJIN (HTC Korea). It provides a guaranteed 5.0V output with ±1% initial tolerance and supports up to 1.5A load current. The device features a 350mV dropout voltage at full load and utilizes a PNP pass element for high efficiency. Packaged in TO-252, it operates within an input range of 2.3V to 26V 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 of 350mV at full load
- 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 manufacturer origin, as HTC Korea produces this component under the TAEJIN brand designation. Confirm the package type matches the required TO-252 footprint and ensure the fixed 5.0V output aligns with system requirements. Check datasheet revision status for any updates to electrical characteristics or pin configurations before finalizing procurement.
Selection Notes
Select this component when a stable 5.0V rail is required with significant current demands up to 1.5A. The TO-252 package offers a balance between thermal dissipation and board space. Ensure the input voltage remains above VOUT plus the dropout voltage across all operating conditions to maintain regulation.
Part Context
This part belongs to the LM2915x series, which includes variants like LM29150 (fixed), LM29151 (enable flag), and LM29152 (adjustable). The RS suffix specifically denotes the surface-mount TO-252 package configuration. The series is designed for applications requiring high accuracy and robust transient response.

FAQ
What is the minimum load current requirement?
The regulator requires a minimum load current of 5mA to swamp leakage currents and maintain proper operation.
How does the device handle overvoltage spikes?
It features transient protection allowing survival from -20V to +60V spikes, with an overvoltage sensor disabling the regulator if input exceeds approximately 35V to 40V.
