STMicroelectronics Voltage Regulator Low Dropout 2.5V to 18V Input 200mA Output Current LDK320AM33R

STMicroelectronics LDK320AM33R is a high-performance low-dropout voltage regulator designed for applications requiring efficient power management across a broad input voltage range of 2.5V to 18V. It delivers a maximum output current of 200 mA while maintaining a low dropout voltage, typically 100 mV at 100 mA load, which ensures minimal voltage loss and efficient power usage.

The regulator operates with a low quiescent current of 60 μA during normal operation and further reduces power consumption to 1 μA in off mode, making it suitable for battery-powered devices and portable electronics. Its high Power Supply Rejection Ratio (PSRR) of 88 dB at 120 Hz along with low output noise provides stable and clean voltage outputs.

An integrated logic-controlled electronic shutdown feature enables power saving by disabling the regulator when not in use. The device is compatible with ceramic capacitors (1 μF) on the output for enhanced stability and noise reduction.

Robust protection features such as current limiting, safe operating area (SOA), and thermal shutdown safeguard the device against overcurrent, thermal overload, and ensure reliable operation in harsh environments. This regulator supports operation over a wide ambient temperature range from -40°C to +125°C, suitable for automotive and industrial applications that demand high reliability.

Typical applications encompass electronic components requiring power regulation, including consumer electronics, communication devices, and embedded systems. The device adheres to RoHS standards ensuring environmental compliance.
