ONSEMI MC7805 5V Positive Linear Voltage Regulator, 1A, TO-252
ONSEMI MC7805 5V, 1A linear voltage regulator in TO-252 package. Features thermal protection for stable power management.
The ONSEMI MC7805BDTRKG is a monolithic, fixed-output, positive linear voltage regulator integrated circuit. Encased in a robust 3-pin TO-252 (DPAK) surface-mount package, it is engineered to provide a stable and reliable 5V DC output from a higher input voltage, making it a fundamental component for power management.
Designed for a wide array of applications, it excels in both local and on-card regulation, simplifying power supply design by eliminating the need for external components. The regulator incorporates several key protective features, including internal current limiting, thermal shutdown, and safe-area compensation, safeguarding both the device and the downstream circuitry from damage due to overloads or excessive heat.
