LDK320M33R Description

Short technical summary and product information.

The STMicroelectronics LDK320M33R is a linear, low dropout (LDO) voltage regulator designed for various power management applications. It provides a stable fixed output voltage of 3.3V and can deliver up to 200mA of current. The regulator features a low dropout voltage of 0.35V at 200mA, making it efficient for battery-powered devices.

 

Key electrical characteristics include a maximum input voltage of 18V, a quiescent current of 90µA, and a maximum supply current of 100µA. Protection features such as over current and over temperature are integrated to enhance reliability. The device operates over a wide temperature range of -40°C to 125°C (TJ).

 

Packaged in a surface-mount SOT-23-5 (SC-74A, SOT-753) case, the LDK320M33R is suitable for space-constrained designs. It is supplied on tape and reel for automated assembly processes. The RoHS3 compliant status indicates adherence to environmental regulations.
