The APL5301-50BC-TR is a low dropout (LDO) linear regulator manufactured by Anpec Electronics. An LDO regulator provides a stable output voltage even when the input voltage is close to the output voltage, making it suitable for battery-powered applications.

Applications

• Battery-powered devices: Provides regulated voltage for microcontrollers and other components in battery-powered devices.
• Portable electronics: Used in smartphones, tablets, and other portable devices.
• Post-regulation: Can be used as a post-regulator to filter noise and improve the stability of switching regulators.
• Microcontroller power supplies: Provides a stable and clean power supply for microcontrollers.
• Sensor power supplies: Regulates the voltage for sensitive sensors.

Features

• Low dropout voltage: Maintains regulation with a small difference between the input and output voltage.
• Fixed output voltage: Provides a fixed 5.0V output voltage.
• Low quiescent current: Minimizes power consumption when the load current is low.
• Overcurrent protection: Protects the regulator from damage due to overcurrent conditions.
• Thermal shutdown: Prevents overheating by shutting down the regulator when the temperature exceeds a safe limit.

Benefits

• Extended battery life: Low quiescent current extends battery life in portable applications.
• Stable voltage regulation: Provides a stable and accurate regulated voltage.
• Improved system performance: Contributes to improved performance and reliability of electronic systems.
• Robust protection: Protects the regulator from damage due to overcurrent and overheating.
• Compact design: Small size allows for easy integration into portable devices.
