The LM7815T is a fixed 15V linear voltage regulator from TAEJIN, delivering up to 1.5A of output current. Housed in a TO-220-3L package, it offers a dropout voltage of just 2V at 1A, making it suitable for applications with moderate input-to-output headroom. With a quiescent current of 8 mA, it maintains efficiency in always-on systems. Ideal for industrial, audio, and embedded power designs.
- High Current Capacity: 1.5A output supports demanding loads without external pass transistors.
- Low Dropout: 2V dropout at 1A allows operation with lower input voltages, reducing power dissipation.
- Stable Fixed Output: 15V fixed output eliminates the need for external resistors, simplifying design.
- Thermal Robustness: TO-220-3L package with metal tab enables efficient heat sinking for continuous operation.
Industrial Power Supplies
Use the LM7815T to create a stable 15V rail for analog circuits, op-amps, and industrial sensors. Its 1.5A capacity handles moderate loads with reliable regulation.
Audio Equipment
Power preamplifiers and audio DSPs with a clean 15V supply. The low quiescent current (8 mA) minimizes noise and heat in sensitive audio paths.
Test & Measurement Instruments
Provide a precise 15V reference for multimeters, oscilloscopes, and calibration tools. The 2V dropout ensures stable operation even with fluctuating input.
Motor Control Circuits
Drive logic and gate drivers in motor controllers. The TO-220 package with a heatsink can dissipate heat effectively at 1.5A continuous load.
Battery Charging Systems
Regulate 15V for charging circuits in lead-acid or lithium battery management. The fixed output simplifies design and ensures consistent charging voltage.
Embedded Systems
Supply 15V to industrial microcontrollers and peripheral ICs that require higher voltage rails. The robust TO-220 package is easy to mount on PCBs.
