WebApr 11, 2024 · Voltage Divider vs. Voltage Regulator. A voltage divider is different from a voltage regulator, which is a circuit that maintains a constant output voltage regardless of changes in the input voltage or load. Voltage regulators are commonly used in power supplies and voltage-sensitive circuits. Q1: What is the purpose of a voltage divider? WebMar 2, 2024 · The LM317 is designed to maintain 1.5V across R1. This is a constant and does not change as long as the input voltage is sufficiently high. Therefore, a voltage across R2 will be developed by the sum of the current: Iadj + 1.5/R1. The output voltage will be 1.5V plus the voltage across R2. – Louis Mar 2 at 1:31
