±12 V / ±15 V and +5 V Regulated Power Supply PCB Board (Compact, Bare PCB)
This PCB is designed for building a regulated DC power supply providing +5 V, +12 V / +15 V, and −12 V / −15 V outputs. Output performance depends on components used and assembly quality.
Output Voltages:
+5 V DC
+12 V or +15 V DC
−12 V or −15 V DC
Output current depends on regulator selection and heat dissipation
Working Voltage:
Input: 12-0-12 VAC or 15-0-15 VAC, 1 A to 2 A (step-down transformer recommended)
Compatible Regulators:
L7805 (+5 V)
L7812 / L7912 (±12 V)
L7815 / L7915 (±15 V)
Connectors:
2 × 2-pin JST / Relimate connectors for +5 V output
1 × 2-pin JST / Relimate connector for +12 V / +15 V output
