Regulator - 7805, 5 Volt, 1A, Linear Voltage Regulator
5V linear regulator with up to 1 amp of current in a TO-220 package. This style of regulator can be found in many power supplies and also modular synth circuits as well as some stomp boxes.
These voltage regulators are monolithic integrated circuits designed as fixed−voltage regulators for a wide variety of applications including local, on−card regulation. These regulators employ internal current limiting, thermal shutdown, and safe−area compensation. With adequate heatsinking they can deliver output currents in excess of 1.0 A (see P-293 for a compatible heat sink). Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents.
Features:
- Output Current in Excess of 1.0 A
- No External Components Required
- Internal Thermal Overload Protection
- Internal Short Circuit Current Limiting
- Output Transistor Safe−Area Compensation
- NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable
- These are Pb−Free Devices

Yes, a 5V Regulator! You find them a lot in Marshall, Mesa Boogie and a lot of other Amp's begin produced today. They are typically used in Rely Switching circuits. You need to add they along with your 12V, 15V & 24V collection which are found in most newer amplifiers.
