LDL1117S30R Description

Short technical summary and product information.

The STMicroelectronics LDL1117S30R is a positive fixed output linear voltage regulator designed for power management applications. It delivers a stable 3V output voltage with a maximum output current of 1.2A. The regulator features a low dropout voltage of 0.6V at 1.2A, making it efficient for applications where the input voltage is close to the output voltage.

 

Key electrical characteristics include an input voltage range up to 18V and protection features such as over current, over temperature, and under voltage lockout (UVLO). The PSRR is rated between 87dB and 65dB across a frequency range of 120Hz to 100kHz, indicating good noise rejection.

 

This component is supplied in a SOT-223 surface mount package, suitable for automated assembly processes. The operating temperature range is -40°C to 125°C (TJ), ensuring reliable performance in various environmental conditions. The LDL1117S30R is a versatile solution for applications requiring a regulated positive voltage supply.
