The STMicroelectronics LK115D33 is a fixed 3.3V positive linear voltage regulator IC designed for surface mount applications. This component delivers a stable output current of 100mA with a typical dropout voltage of 0.17V at 60mA. It features an enable pin for control and offers protection against overcurrent and overtemperature conditions. The device operates over an extended temperature range of -40°C to 125°C and supports input voltages up to 20V. Power Supply Rejection Ratio (PSRR) ranges from 79dB to 57dB across a frequency band of 120Hz to 10kHz. The LK115D33 is packaged in an 8-SOIC format. This regulator is suitable for use in automotive, industrial, and consumer electronics applications requiring reliable voltage regulation.
