Circuit Board Voltage Regulators
Safely power low-voltage components in circuits with a high-voltage source. These regulators turn high-voltage inputs into lower, more stable outputs.
Regulators with an adjustable output voltage let you fine-tune the output to best fit your circuit. To adjust the output voltage, connect them to two resistors (not included). The resistance values determine your output voltage.
Dropout voltage is the minimum required difference between the input voltage and your regulator’s output voltage.
