The XC6219B28ADR-G is a low dropout (LDO) regulator manufactured by Torex Semiconductor Ltd. LDO regulators are used to provide a stable and regulated output voltage from a higher input voltage. They are known for their low dropout voltage, meaning they can maintain regulation even when the input voltage is only slightly higher than the output voltage.

Applications

• Power management in portable devices
• Battery-powered applications
• Post-regulation for switching power supplies
• Noise-sensitive circuits
• Microcontroller power supplies

Features

• Output Voltage: 2.8V (Indicated by "B28" in the part number)
• Input Voltage Range: Wide input voltage range (check datasheet for precise range, typically 1.8V to 6.0V)
• Low Dropout Voltage: Low dropout voltage (check datasheet for the specific dropout voltage at a given current)
• Output Current: Moderate output current capability (check datasheet for the maximum output current, e.g., 200mA to 500mA)
• Low Quiescent Current: Low quiescent current (typically a few microamperes)
• Protection Features: Overcurrent protection (OCP) and thermal shutdown (TSD)
• Package: SOT-25 or similar small surface-mount package

Benefits

• Stable Output Voltage: Provides a stable and regulated output voltage, even with variations in input voltage or load current.
• Low Dropout Voltage: Maintains regulation with a small difference between input and output voltage, maximizing efficiency.
• Low Power Consumption: Low quiescent current minimizes power loss.
• Compact Size: Small package size allows for use in space-constrained applications.
• Protection Features: Protects the regulator and the load from damage due to fault conditions.
