STMicroelectronics Voltage Regulator 18V Low Drop 200mA LDK320M-R

STMicroelectronics LDK320M-R is a precision low dropout voltage regulator designed for applications requiring efficient and stable voltage regulation with input voltages from 2.5 V to 18 V and output currents up to 200 mA.

This regulator features a low dropout voltage of typically 100 mV at a 100 mA load, making it suitable for battery-powered equipment and compact power supplies.

With a low quiescent current of 60 microamperes in operation and a minimal 1 microampere during shutdown, it offers high power efficiency and extended battery life. The device provides a high power supply rejection ratio (PSRR) of 88 dB at 120 Hz, significantly reducing output voltage noise for sensitive electronic circuits.

The output voltage is stabilized using a ceramic capacitor of 1 μF, ensuring stable operation under varying load conditions. Safety features include current limiting, SOA protection, and thermal shutdown to prevent damage under fault conditions.

Operating over a wide temperature range from -40 °C to 125 °C, this voltage regulator is well suited for industrial, automotive, and commercial electronics requiring robust and reliable voltage regulation.

Input voltage range from 2.5 V to 18 V allows flexible power supply options. Typical dropout voltage of 100 mV at 100 mA ensures efficient voltage regulation. Low quiescent current of 60 μA during operation and 1 μA in off mode reduces power consumption.

High power supply rejection ratio (PSRR) of 88 dB at 120 Hz minimizes voltage noise. Output stabilized with a ceramic capacitor of 1 μF for reliable operation. Includes logic-controlled electronic shutdown capability for power saving.

Provides current limiting, safe operating area (SOA), and thermal protections for enhanced reliability. Operates within a temperature range of -40 °C to 125 °C suitable for diverse environments.

This product is ideal for use in electronics, industrial manufacturing, automotive systems, and power management applications where efficient and reliable voltage regulation is critical.
