A precision resistor network used in power supply feedback loops to regulate output voltage.
A feedback resistor network is a critical electronic component in power supply regulation circuits, typically consisting of multiple precision resistors arranged in a specific configuration (often voltage divider topology) to sample the output voltage and provide a proportional feedback signal to the control IC. This network establishes the closed-loop control that maintains stable output voltage despite load variations, input fluctuations, and temperature changes.

Failure typically causes loss of voltage regulation - output may become unstable (oscillate), overvoltage (damaging loads), or undervoltage (system malfunction). Common failures include resistor drift, open circuit, or short circuit.
Calculate based on desired output voltage and regulator IC reference voltage using Vout = Vref × (1 + R1/R2). Choose precision resistors with low temperature coefficient and adequate power rating for your application.
While possible, integrated networks provide better matching, tracking, and space efficiency. Discrete resistors may have mismatched temperature coefficients causing voltage drift.
