LDK130M18RY Description

Short technical summary and product information.

The STMicroelectronics LDK130M18RY is a linear low-dropout (LDO) voltage regulator designed for applications requiring stable voltage regulation with low noise and low quiescent current. It provides a fixed output voltage of 1.8V and can supply up to 300mA of current.

 

Key electrical specifications include an input voltage range from 1.9V to 5.5V, a typical quiescent current of 30 µA, and a PSRR of 55 dB at 120Hz to 10kHz. The device offers excellent line and load regulation, with values of 0.05%/V and 0.006%/mA respectively. Protection features such as over-current and over-temperature are integrated for enhanced reliability.

 

This LDO voltage regulator is housed in a compact SOT-23-5 (SC-74A, SOT-753) surface-mount package, making it suitable for space-constrained designs. The operating temperature range is from -40°C to +125°C (TJ), ensuring performance in various environmental conditions. Its low noise and low quiescent current characteristics make it ideal for battery-powered devices and automotive applications.
