Low Dropout (LDO) Linear Voltage Regulators, 400mA, ON Semiconductor

This remarkable ON Semiconductor linear voltage regulator comes under the LDO (Low dropout) family. These products are monolithic integrated circuits designed as fixed-voltage regulators for a wide range of applications including local, on-card regulation. LDO voltage regulators may offer fast transient response, wide input voltage range, low quiescent current and low noise with high PSRR.

Features and Benefits
• Internal thermal overload protection
• Internal short circuit current limiting
• Output transistor safe – area compensation
• These are Pb-Free devices
• Output current in access of 400mA
• Output Voltage 3.3V
• Package type: SOT-223
• Accuracy +2%

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.
