STMicroelectronics Voltage Regulator Low Dropout 2.5-18V Input 200mA Output Current LDK320M-R

STMicroelectronics LDK320M-R is a high-performance low dropout (LDO) voltage regulator designed to operate with input voltages ranging from 2.5 V up to 18 V. It features a maximum output current of 200 mA and a typical dropout voltage of only 100 mV at a 100 mA load, making it ideal for power-sensitive and noise-sensitive applications.

This Voltage Regulator offers low quiescent current of 60 μA during normal operation, which reduces power consumption, and an ultra-low 1 μA in shutdown mode. The high power supply ripple rejection (PSRR) of 88 dB at 120 Hz ensures stable and clean output voltage suitable for sensitive analog and digital circuits.

The device includes built-in logic-controlled electronic shutdown for additional power savings and is designed to be compatible with a ceramic output capacitor of 1 μF, aiding in stable and reliable performance. Protection features include current limiting, safe operating area (SOA), and thermal shutdown protections to safeguard the device under fault conditions.

Operating temperature extends from -40 °C to 125 °C, suitable for a broad range of industrial and consumer environments. Typical use cases include power management in electronic components, industrial automation systems, instrumentation, and embedded system applications.
