LDK120PU18R Description

Short technical summary and product information.

The STMicroelectronics LDK120PU18R is a linear voltage regulator designed for efficient power management. It provides a stable 1.8V output voltage with a maximum output current of 200mA. The device operates from an input voltage of up to 5.5V and features a low quiescent current of 60 µA.

 

Key electrical characteristics include a voltage dropout of 0.3V at 200mA and a Power Supply Rejection Ratio (PSRR) of 55dB across a frequency range of 120Hz to 10kHz. Protection features such as Over Current and Over Temperature are integrated to ensure reliable operation.

 

This regulator is housed in a compact 6-DFN (1.2x1.3) package, suitable for surface mount applications. The operating temperature range is -40°C to 125°C, making it suitable for a variety of environmental conditions. The 'Enable' control feature allows for power management.

 

Compliance information indicates RoHS3 compliance, Moisture Sensitivity Level (MSL) 1, and REACH unaffected status, though these are based on unverified data.
