Datasheet

High-Current 800mA Low-Dropout Linear Voltage Regulator IC for Stable DC Power Conversion (SOT-223-4 Package)

The LM1117MPX-3.3/NOPB is a reliable low-dropout (LDO) linear voltage regulator designed to deliver a fixed 3.3V output with load currents up to 800mA. It supports input voltages up to 15V, making it suitable for converting higher DC input rails into a stable 3.3V supply for digital and embedded electronics. The device maintains regulation even with a small difference between input and output voltage, which helps improve efficiency in compact power designs.

Packaged in a SOT-223-4 surface-mount format, this regulator offers good thermal performance when mounted with proper PCB copper area. It is widely used in microcontroller systems, development boards, networking devices, industrial electronics, and IoT hardware where a dependable 3.3V rail is required for logic circuits and communication modules.

Key Features:

  • Fixed Output Voltage: Regulated 3.3V output for digital circuits
  • High Output Current: Supports up to 800mA load current
  • Wide Input Voltage Range: Accepts input voltages up to 15V
  • Low-Dropout Design: Efficient regulation with minimal voltage headroom
  • Thermally Efficient Package: SOT-223-4 package suitable for surface-mount PCB designs
  • Protection Features: Built-in current limiting and thermal shutdown
  • Typical Applications: Microcontrollers, embedded systems, communication modules, and industrial control boards
