LDK220M-R Description

Short technical summary and product information.

The STMicroelectronics LDK220M-R is a linear voltage regulator designed for adjustable positive voltage output. It features a low quiescent current of 90µA and a maximum dropout voltage of 0.35V at 200mA. The device offers protection against over current and over temperature conditions, with an enable control feature.

This regulator operates within a temperature range of -40°C to 125°C and provides a PSRR of 60dB to 45dB across the 120Hz to 10kHz frequency range. The output voltage is adjustable, and the device is rated for a maximum output voltage of 13.2V.

The LDK220M-R is packaged in a SOT-23-5 (SC-74A, SOT-753) surface mount case. It is designed for applications requiring stable and adjustable voltage regulation with low power consumption.
