LK115D30 Description

Short technical summary and product information.

The STMicroelectronics LK115D30 is a highly efficient linear low-dropout (LDO) voltage regulator designed for various applications. It provides a stable fixed output voltage of 3V and can deliver up to 100mA of current. The regulator features a very low dropout voltage of 0.17V typical at 60mA, making it suitable for battery-powered systems where power efficiency is critical.

 

Key electrical characteristics include a wide input voltage range up to 18V and excellent power supply rejection ratio (PSRR) of 79dB to 57dB. The device operates over a temperature range of -40°C to 125°C and includes internal protection features such as over-current and over-temperature shutdown.

 

Designed for ease of use, the LK115D30 requires only a 2.2µF capacitor for stability. It is available in a compact 8-SOIC surface-mount package, facilitating space-saving designs on printed circuit boards. The regulator also features an enable pin for logic-controlled shutdown, allowing for further power consumption reduction when not in use.
