Working Principles

The LM3000ASQX/NOPB operates as a linear voltage regulator. It regulates the input voltage to provide a stable output voltage. The feedback pin (FB) is used to set the desired output voltage by connecting an external resistor divider network. The enable pin (EN) controls the device's on/off state.

When the input voltage exceeds the dropout voltage, the IC maintains a constant output voltage. If the input voltage drops below the dropout voltage, the output voltage decreases proportionally. The IC also includes protection features to prevent damage from overcurrent and excessive temperature.
