The LM29152RS is a high-performance low dropout linear regulator from TAEJIN, delivering a fixed 25V output with up to 1.5A of current. Its low 0.6V dropout voltage at full load ensures efficient operation even with minimal input-to-output headroom. Housed in a compact TO-252-5L package, it offers excellent thermal performance and reliability for demanding industrial and automotive applications.
- High Current Capacity: 1.5A output supports power-hungry loads without external pass transistors.
- Low Dropout Voltage: 0.6V at 1.5A minimizes power dissipation and improves efficiency in battery-powered systems.
- Fixed 25V Output: Eliminates the need for external resistor dividers, simplifying design and reducing BOM cost.
- Robust TO-252-5L Package: Provides excellent thermal dissipation for continuous high-current operation.
High-Current Industrial Power Supplies
The 1.5A output capability and 25V fixed output make it ideal for powering industrial sensors, actuators, and control circuits that require a stable, high-voltage rail.
Automotive Electronics
With a low dropout of 0.6V at full load, the LM29152RS efficiently regulates from a 26V automotive battery bus, providing clean power to ECUs and infotainment systems.
Telecom and Networking Equipment
Its robust 1.5A current rating supports line cards, routers, and base stations where a regulated 25V supply is needed for analog front-ends and RF drivers.
Battery-Powered Devices
The low dropout voltage extends battery life by allowing operation until the battery voltage drops close to 25V, maximizing usable capacity in 26-28V battery packs.
Test and Measurement Instruments
Precision instruments requiring a stable 25V reference rail benefit from the LM29152RS's low output noise and tight regulation under varying load conditions.
LED Lighting Drivers
For high-voltage LED strings, this regulator provides a constant 25V supply to constant-current drivers, ensuring consistent brightness and long LED life.
