Compact 3.3V Low Dropout Linear Voltage Regulator for Portable and Embedded Electronics

The AP2127K-3.3TRG1 is a fixed 3.3V low dropout (LDO) linear voltage regulator designed to deliver stable and efficient power for low-voltage electronic circuits. With a maximum output current of 300mA and support for input voltages up to 6V, this regulator is ideal for powering microcontrollers, sensors, wireless modules, and other low-power digital components. Its compact SOT-23-5 surface-mount package makes it suitable for space-constrained PCB designs used in portable devices and embedded systems.

This LDO regulator offers low dropout voltage and low quiescent current, helping improve energy efficiency in battery-powered applications. It also includes built-in protection features such as current limiting and thermal shutdown to ensure safe operation under varying load conditions. The AP2127 series is widely used in consumer electronics, IoT devices, development boards, and portable instrumentation where stable 3.3V power is required.

Key Features

  • Fixed 3.3V Output Voltage – Provides a stable power supply for microcontrollers and digital circuits.
  • 300mA Output Current Capability – Suitable for powering embedded modules and peripheral components.
  • 6V Maximum Input Voltage – Supports a range of low-voltage power sources including batteries and adapters.
