Dual Voltage Regulator — threeterminal regulator power supply module Key benefits Provides clean, regulated dual 12 V rails to power circuits that require symmetric supplies, eliminating the need to design discrete regulator stages. Accepts either AC or DC input within a wide range, simplifying compatibility with common transformers and DC adapters. Protects downstream electronics by delivering stable positive and negative outputs when fed with proper dual input voltages. Main features and specifications Output: dual 12 V regulated rails (±12 V configuration for symmetric supply use). Regulator type: threeterminal regulator power supply module for straightforward, reliable regulation. Input voltage (DC): DC 15 to 24 V — requires both positive and negative input rails (dual supply). Input voltage (AC): AC 12 to 24 V — designed for positive and negative dualvoltage AC input. Input requirement: dual (positive and negative) input must be provided; the module does not convert a singleended input into dual rails. Compatibility and use Designed for any device or circuit that needs stable ±12 V rails, including analog, audio, sensor, and control electronics. Compatible with AC transformer secondaries (12–24 VAC) or DC dualrail supplies (15–24 V DC) as long as both positive and negative inputs are present. Use cases include prototyping, repairs, and integration into custom power subsystems. Performance and installation notes Intended to provide regulated, symmetric voltages when installed with the correct dual input; stable output depends on maintaining input within specified ranges. Ensure correct polarity and presence of both positive and negative input rails before powering the module. Follow standard wiring and grounding practices for dualrail systems to avoid shorts or reversepolarity damage. Practical application examples Audio equipment: supply ±12 V rails for preamplifiers, opamp stages, and active filters that require symmetric power. Analog instrumentation: power differential amplifiers, ADC driver circuits, and sensor signal conditioning modules that need stable +/12 V. DIY and bench projects: separate discrete regulator designs with a readymade module when building test fixtures or repairing devices that expect dual rails. Safety and compatibility reminders Do not attempt to feed the module from a singleended supply expecting it to generate both polarities; a dual (positive and negative) input is required. Keep input voltages within the specified ranges (DC 15–24 V or AC 12–24 V) to ensure proper regulation and prevent damage.
