LDK120C15R Description

Short technical summary and product information.

The LDK120C15R is a fixed output LDO voltage regulator from STMicroelectronics, providing a stable 1.5V output with up to 200mA of current. It features a low dropout voltage of 0.3V maximum at 200mA load, making it suitable for battery-powered applications. The quiescent current is only 60µA, contributing to extended battery life. Power supply rejection ratio (PSRR) is 55dB over the 120Hz to 10kHz range, ensuring clean output. The regulator includes over-current and over-temperature protection, as well as an enable control pin for on/off operation. The operating temperature range spans -40°C to 125°C. The part is housed in a surface-mount SOT-323-5 package, ideal for compact designs.
