STMicroelectronics Voltage Regulator LDL1117S30R 18V 1.2A Surface Mount SOT-223 3-Pin LDL1117S30R

STMicroelectronics LDL1117S30R is a high-performance voltage regulator designed for electronic components requiring stable and efficient power regulation. The device operates over a wide input voltage range of 2.5V to 18V and delivers a continuous output current up to 1.2A, making it ideal for various industrial and consumer power management applications.

This regulator utilizes a SOT-223 3-pin surface mount package facilitating easy PCB integration and compact design. The low typical dropout voltage of 350mV at full load ensures higher efficiency and extended battery life in portable devices. It incorporates multiple protection features including internal thermal shutdown, current limit, and safe operating area protections to enhance reliability under varying load conditions.

With a high power supply rejection ratio of 87 dB at 120 Hz, the LDL1117S30R minimizes the influence of input voltage noise, thereby ensuring consistent and clean output voltage. The device is suitable for use in switching mode power supplies (SMPS), secondary linear regulators in DC-DC converters, and other industrial-grade electronics requiring robust voltage regulation.

The operating temperature range from -40°C to 125°C supports harsh environments and automotive applications, although this particular model is not certified for automotive standards. Its compact dimensions of 6.7mm length, 3.7mm width, and 1.7mm height make it appropriate for densely populated circuit boards.

This voltage regulator supports positive polarity voltage regulation. The compact SOT-223 package offers surface mount convenience with three pins for simple connectivity. Incorporates quiescent current of 500μA minimizing standby power consumption.

Maximum operating temperature rated at 125°C ensures durability in demanding applications. Maximum input voltage of 18V with a minimum input voltage threshold of 2.6V gives flexibility in power source selection. Ideal for embedded systems, industrial automation, power management ICs, and electronic instrumentation.
