Engineered with STMicroelectronics' advanced semiconductor technology, this voltage regulator delivers exceptional stability and efficiency. Its low dropout voltage of 1.3V at maximum load current enables operation in systems with limited headroom, while maintaining excellent line and load regulation. The device's 75dB PSRR (Power Supply Rejection Ratio) at 120Hz ensures minimal noise transmission from input to output, crucial for sensitive analog circuits.
Designed for modern electronics manufacturing, the LD1117D33CTR features a compact 8-SOIC surface-mount package (3.90mm width) that facilitates automated assembly processes. The tape & reel packaging format supports efficient production line integration while maintaining component quality during handling and storage.
Key Features:
Integral protection circuitry includes both overcurrent and overtemperature safeguards, preventing damage from fault conditions without compromising performance. The device's quiescent current of just 10mA minimizes power loss during normal operation, contributing to overall system efficiency.
Industrial equipment designers benefit from the regulator's wide operating temperature range (-40°C to 125°C), ensuring reliable performance in harsh environments. Applications spanning from industrial automation systems to embedded electronics can leverage this device's stability and robustness to maintain consistent power delivery.
Compared to switching regulators, the LD1117D33CTR offers simpler implementation with fewer external components required. Its fixed output voltage configuration eliminates the need for precision resistor dividers, reducing design complexity while maintaining accuracy. The linear topology ensures minimal electromagnetic interference (EMI), making it particularly suitable for RF-sensitive applications.
As part of STMicroelectronics' comprehensive power management portfolio, this regulator demonstrates the company's commitment to delivering innovative solutions that balance performance, reliability, and design simplicity. Engineers can confidently integrate the LD1117D33CTR into their designs, knowing they're using a component that meets rigorous industry standards for quality and longevity.
