The LM7808T is a fixed 8V linear voltage regulator from TAEJIN, capable of delivering 1.5A output current. Packaged in a TO-220-3L, it features a 2V dropout voltage and 8 mA quiescent current. This regulator is well-suited for automotive, industrial, and embedded applications requiring a stable 8V supply with minimal external components.
- High Output Current: 1.5A rating supports multiple loads and peripheral circuits.
- Simple Fixed Output: 8V fixed voltage eliminates feedback network design.
- Low Quiescent Current: 8 mA reduces standby power consumption in battery-operated systems.
- Durable Package: TO-220-3L with metal tab allows easy heatsink attachment for thermal management.
Microcontroller Power Rails
Supply a stable 8V rail for 8-bit and 16-bit microcontrollers that operate at 8V logic levels. The 1.5A capacity supports multiple peripherals.
Relay and Solenoid Drivers
Power relay coils and solenoids requiring 8V. The TO-220 package handles the inrush current and thermal stress of inductive loads.
Automotive Electronics
Regulate 8V for sensors and ECUs in automotive environments. The robust package and 2V dropout tolerate battery voltage fluctuations.
Communication Interfaces
Provide 8V for RS-232 transceivers and CAN bus controllers. Low quiescent current (8 mA) is ideal for always-on communication modules.
Battery-Powered Devices
Use with 10-12V battery packs to create an 8V rail for portable instruments. The low dropout maximizes battery utilization.
LED Lighting Systems
Drive constant-voltage LED strips rated at 8V. The 1.5A output can power multiple LED strings with consistent brightness.
