LDK120PU32R Description

Short technical summary and product information.

The LDK120PU32R is a fixed-output positive linear voltage regulator (LDO) manufactured by STMicroelectronics. It provides a regulated 3.2V output with a maximum output current of 200mA. The device features a low dropout voltage of 0.3V at 200mA load, making it suitable for battery-powered and low-voltage applications. The quiescent current is only 60µA, contributing to high efficiency in standby and light-load conditions.

 

The regulator includes over-current and over-temperature protection features, enhancing system reliability. It offers a power supply rejection ratio (PSRR) of 55dB over a frequency range of 120Hz to 10kHz, providing good noise filtering. The enable control feature allows the output to be turned off for power savings.

 

The LDK120PU32R is housed in a compact 6-XFDFN package (6-DFN 1.2x1.3mm) and is designed for surface mount assembly. It operates over a junction temperature range of -40°C to 125°C, making it suitable for industrial and automotive environments. The input voltage range extends up to 5.5V.
