LDK120PU12R Description

Short technical summary and product information.

The STMicroelectronics LDK120PU12R is a linear voltage regulator designed for efficient power management. It provides a stable, fixed 1.2V output voltage with a maximum output current of 200mA. The device operates from a supply voltage of up to 5.5V and exhibits a low dropout voltage of 0.3V at 200mA, making it suitable for battery-powered applications.

 

Key electrical characteristics include a quiescent current of 60 µA 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 device reliability. The regulator is controlled via an Enable pin.

 

Packaged in a compact 6-DFN (1.2x1.3) surface-mount form factor, the LDK120PU12R is designed for applications where space is limited. It operates across an industrial temperature range of -40°C to 125°C, ensuring performance in various environmental conditions.
