The LT1763IDE-3.3#PBF is a high-performance, low dropout voltage regulator from Linear Technology, designed to deliver a fixed output of 3.3 volts. This component is known for its low noise operation, making it an excellent choice for sensitive RF and audio applications where power supply noise can adversely affect performance.

Key Features

• Low Noise Output: With a low noise output of only 20µVRMS over a 10Hz to 100kHz bandwidth, this regulator ensures a clean and stable voltage supply.
• Low Dropout Voltage: The device can maintain regulation with a minimal difference between the input and output voltages, which is beneficial in battery-powered applications where maximizing the use of available input voltage is critical.
• High Output Current: Capable of delivering up to 500mA of continuous output current, it is suitable for a wide range of applications.
• Stable with Low ESR Capacitors: The LT1763IDE-3.3#PBF remains stable with ceramic, tantalum, or aluminum electrolytic capacitors, offering flexibility in design.
• Overtemperature and Overcurrent Protection: Built-in protection features safeguard the device and the load from adverse conditions.
• No Protection Diodes Needed: Internal circuitry eliminates the need for external protection diodes, simplifying design and reducing component count.
• Fixed Output Voltage: Pre-set 3.3V output eliminates the need for external resistors to set the voltage, thereby simplifying the design and reducing component count.
