Applications
Linear regulators are simple voltage regulator circuits commonly adopted in electronics. A Linear voltage regulator uses a closed feedback loop to bias a pass element to maintain a steady voltage across output terminals. Linear regulators are most commonly highly integrated, which include the pass element and feedback loop.

LDO (Low Dropout) Linear Voltage Regulators, ON Semiconductor

The Low dropout or LDO is a linear voltage regulator. We have a wide range of linear regulators. The LDO regulator can operate with a small input–output differential voltage. LDO voltage regulators may offer fast transient response, wide input voltage range, low quiescent current and low noise with high PSRR.
