STMICROELECTRONICS 7805 Fixed Linear Voltage Regulator, 5V 1.5A, TO-220FP
STM 7805 linear voltage regulator. Fixed 5V, 1.5A output from 10-35V input. TO-220FP package with thermal & short-circuit protection.
The STMICROELECTRONICS L7805ACP is a highly reliable positive voltage regulator, presented in a robust 3-pin TO-220FP package. This fixed regulator is designed to provide efficient local on-card regulation, effectively eliminating the distribution challenges and instability often associated with single-point regulation systems.
Engineered for durability, this integrated circuit incorporates comprehensive internal protection mechanisms, including current limiting, thermal shutdown, and safe operating area (SOA) protection, making it exceptionally resilient and difficult to damage under typical operating conditions.
Key Features & Specifications
- Input Voltage Range: Accepts a wide supply voltage from 10V to 35V.
- Fixed Output: Provides a stable 5V DC output voltage.
- High Output Current: Capable of delivering a continuous output current of up to 1.5A.
- Built-in Protections: Features thermal overload protection, short-circuit protection, and output transition SOA protection for enhanced safety and component longevity.
- Excellent Regulation: Offers a high supply voltage rejection of 68dB (at VI = 8V-18V, f = 120Hz, IO = 500mA), ensuring a clean and stable output even with a noisy or fluctuating input.
- Low Dropout: Has a dropout voltage of just 2V at a 1A load.
- Low Output Resistance: Features a low output resistance of 17mΩ at 1kHz.
This regulator is a fundamental component for power management tasks, providing a simple and effective solution for stepping down a higher DC voltage to a precise, fixed 5V level required by countless digital circuits, microcontrollers, and other electronic components.
