STMicroelectronics L7805ABV-DG, 1 Low Dropout Voltage, Voltage Regulator 1.5A, 1.8 → 5 V 3-Pin, TO-220

The STMicroelectronics Positive voltage regulator, This regulator can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type embeds internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.

Thermal overload protection
Short circuit protection
Output transition SOA protection
