L5150CSTR General Description

The L5150CS is a state-of-the-art linear regulator that offers microprocessor control functions alongside exceptional voltage regulation capabilities. Equipped with features such as power on reset, low voltage reset, and early warning functionalities, this regulator is tailor-made for applications where accuracy and stability are paramount. Operating at a typical quiescent current of just 55 μA at low output currents, the L5150CS excels in energy efficiency while delivering reliable performance. On-chip trimming ensures high output voltage accuracy of ±2%, maintaining precision even in challenging conditions like temperature variations, line changes, and load fluctuations. The early warning circuit continuously monitors input voltage against an internal reference, while the adjustable output voltage reset threshold can be fine-tuned down to 3.5 V using an external voltage divider. With a maximum input voltage of 40 V and internally limited output current, the L5150CS offers safe and dependable operation in diverse scenarios. Moreover, the internal temperature protection mechanism safeguards the regulator output, ensuring the safety and longevity of your system. And with the added advantage of needing only a low-value ceramic capacitor for stability, the L5150CS stands out as the ideal choice for precise and efficient voltage regulation
