• Battery-powered applications

Features

• Low Dropout Voltage: Maintains stable output even with a small difference between input and output voltages.
• Overcurrent Protection: Protects the device and the connected load from excessive current draw.
• Thermal Shutdown: Prevents damage from overheating by automatically shutting down when the temperature exceeds a safe limit.
• Small Package: Compact size allows for efficient use of board space.
• High Accuracy Output Voltage: Provides a precisely regulated voltage for sensitive applications.

Benefits

• Stable Power Supply: Ensures consistent performance of electronic devices by providing a regulated voltage.
• Protection Against Overload: Prevents damage to the regulator and connected components in the event of an overcurrent condition.
• Enhanced Reliability: Thermal shutdown feature enhances the reliability and longevity of the device.
• Space Saving: Small package allows for integration into compact designs without compromising performance.
• Improved Efficiency: Low dropout voltage contributes to higher efficiency, extending battery life in portable applications.

Technical Specifications: While the exact specifications can vary slightly depending on the specific configuration, typical parameters include an input voltage range of 2.5V to 5.5V, an output voltage that can be factory-set (e.g., 1.8V, 3.3V), a dropout voltage typically around 200mV at rated current, and an output current capability of up to 300mA. The device also features a low quiescent current, which minimizes power consumption when the regulator is in standby mode. Package options often include small outline transistor (SOT) packages like SOT-23 or similar variants.
