Working Principle
NPN pass transistor with internal bandgap reference and error amplifier maintains 5V output. Current limit (typically 3.4A) protects against overload. Thermal shutdown activates at 150°C junction temperature. The D2PAK package with exposed tab provides low thermal resistance for high-power dissipation without external heatsink.
Applications
- 5V logic rail from 12V/24V
- Industrial control power
- Automatile ECU 5V supply
- General-purpose regulation
