LE33CZ-TR Description

Short technical summary and product information.

The STMicroelectronics LE33CZ-TR is a positive fixed output linear voltage regulator designed for power management applications. It provides a stable 3.3V output voltage with a maximum output current of 100mA. The regulator features a low dropout voltage of 0.5V at 100mA, making it suitable for applications where efficient power usage is critical.

 

Key electrical characteristics include an input voltage range up to 18V and a quiescent current of 1mA. Protection features such as over current and over temperature protection are integrated to ensure reliable operation. The device also offers good power supply ripple rejection (PSRR) between 80dB and 60dB across a frequency range of 120Hz to 10kHz.

 

This component is supplied in a TO-92-3 through-hole package, facilitating easy integration into circuit designs. The operating temperature range is from -40°C to 125°C, allowing for use in various environmental conditions. The RoHS status is compliant with RoHS3 standards, and it has an MSL rating of 1.
