This is the basic L7809 voltage regulator, a three-terminal positive regulator with a 9V fixed output voltage. This fixed regulator provides a local regulation, internal current limiting, thermal shut-down control, and safe area protection for your project. Each one of these voltage regulators can output a max current of 1.8A peak.

Features:

• Output Voltage: 9V
• Output Current: 1.8A peak
• Thermal Overload Protection
• Short Circuit Protection
• Output Transition SOA Protection
