The SGM2200-1.8YN3LG/TR is a low-dropout (LDO) voltage regulator manufactured by SG Micro Corp. LDO regulators are used to provide a stable and regulated output voltage from a higher input voltage, even when the input voltage is close to the desired output voltage. They are commonly used in battery-powered devices and other applications where a stable voltage supply is critical.

Applications

• Portable electronic devices (e.g., smartphones, tablets)
• Battery-powered equipment
• Post-regulation for switching power supplies
• Microcontroller power supplies
• Sensor power supplies

Features

• Low dropout voltage: Maintains regulation even with a small difference between input and output voltage.
• Low quiescent current: Minimizes power consumption in standby mode.
• High output accuracy: Provides a stable and precise output voltage.
• Overcurrent protection: Protects the regulator and the load from damage due to excessive current.
• Thermal shutdown: Prevents overheating and potential damage to the regulator.

Benefits

• Extended battery life: Low quiescent current minimizes power consumption in portable devices.
• Stable voltage supply: Provides a consistent and reliable voltage for sensitive electronic components.
• Improved system performance: Accurate output voltage ensures optimal performance of connected devices.
• Enhanced reliability: Protection features prevent damage from overcurrent and overheating.
• Simplified design: Integrated features reduce the number of external components required.

The SGM2200-1.8YN3LG/TR operates by using an internal feedback loop to regulate the output voltage. A control circuit adjusts the output transistor to maintain the desired output voltage, even when the input voltage or load current changes. The low dropout voltage is achieved by using a pass transistor with a low on-resistance, which minimizes the voltage drop across the regulator. The low quiescent current is achieved by minimizing the current consumption of the internal circuitry.

Technical Specifications: The SGM2200-1.8YN3LG/TR has a fixed output voltage of 1.8V. Review the SG Micro Corp datasheet for specifics such as input voltage range, output current capability, dropout voltage at a given current, quiescent current, and thermal resistance. Be mindful of the operating temperature range and package type.
