LDK120DM33R Description

Short technical summary and product information.

The ST LDK120DM33R is a linear low-dropout (LDO) voltage regulator designed for various power management applications. It provides a stable, fixed output voltage of 5V and can deliver up to 1A of current. The regulator exhibits a low dropout voltage of 1.3V at 800mA, making it efficient for applications where the input voltage is close to the output voltage.

 

Key electrical characteristics include a maximum input voltage of 15V and a quiescent current of 6mA. The device offers good ripple rejection of 70dB at 120Hz. It operates within a junction temperature range of -20°C to 125°C.

 

The LDK120DM33R is supplied in a TO-261-4, TO-261AA package, commonly known as SOT-223-3, suitable for surface mounting. This package type facilitates integration into compact electronic designs.

 

Environmental compliance includes RoHS3 compliance and REACH unaffected status. The Moisture Sensitivity Level (MSL) is rated at 3 (168 Hours).
