The LM1117GS-3.3V is a low dropout (LDO) voltage regulator manufactured by TAEJIN and also produced by HTC Korea. It provides a stable 3.3V output voltage with a low dropout voltage, allowing it to operate efficiently even when the input voltage is only slightly higher than the desired output voltage. This LDO regulator is widely used in various electronic applications, including portable devices, computer peripherals, and power management circuits.

Applications:

• Post Regulation for Switching Supplies
• Battery Chargers
• Active SCSI Terminators
• Microprocessor Power Supplies
• Portable Electronics

Features:

• Low Dropout Voltage: Operates with a minimal difference between input and output voltage.
• Output Current: Capable of delivering a specific output current.
• Internal Current Limiting: Protects the regulator from overload conditions.
• Thermal Shutdown: Prevents damage from excessive heat.
• Fixed Output Voltage: Provides a precise and stable 3.3V output.

Benefits:

• High Efficiency: Low dropout voltage minimizes power loss and improves efficiency.
• Overload Protection: Current limiting and thermal shutdown enhance reliability.
• Stable Output Voltage: Provides a consistent and accurate voltage supply.
• Simplified Design: Requires minimal external components.
• Compact Size: Small package size allows for use in space-constrained applications.

Additional Details:

The LM1117GS-3.3V typically comes in a surface-mount package (e.g., SOT-223). Key specifications include input voltage range, output current capability, dropout voltage at various load currents, and thermal resistance. The regulator requires input and output capacitors for stability; refer to the datasheet for recommended capacitor values and types. This LDO regulator is a reliable and cost-effective solution for providing a stable 3.3V power supply in a wide range of electronic devices.
