Product Overview

The LDI51-1.8EN is a high-performance low dropout (LDO) voltage regulator from Diotec Semiconductor, designed to deliver a stable 1.8V fixed output with up to 500mA current capability. This precision voltage regulator features an ultra-low dropout voltage of just 0.12V at 100mA, making it ideal for battery-powered applications and noise-sensitive circuits.

Key Features & Benefits

  • Fixed 1.8V Output: Provides precise voltage regulation for microcontrollers, FPGAs, and other digital ICs
  • 500mA Output Current: Sufficient power delivery for most embedded system applications
  • Low Dropout Voltage: Only 0.12V dropout at 100mA ensures efficient operation even with tight input-output voltage margins
  • Excellent PSRR: 80dB power supply rejection ratio at 1kHz filters out input noise effectively
  • Compact SOT-23-5 Package: Space-saving surface mount design perfect for high-density PCB layouts
  • Wide Input Voltage Range: Accepts up to 15V input voltage for flexible power supply design
  • Built-in Protection: Over-temperature protection safeguards your circuit from thermal damage
  • Enable Control: Allows for power sequencing and shutdown functionality
  • Extended Temperature Range: Operates reliably from -40°C to 125°C (junction temperature)
  • RoHS Compliant: Environmentally friendly and meets international standards

Applications

The LDI51-1.8EN voltage regulator is perfectly suited for:

  • Microcontroller and microprocessor power supplies
  • FPGA and ASIC core voltage regulation
  • Battery-powered portable devices
