The Belling BL9198-15BAPRN is a low dropout (LDO) regulator that has been designed with a SOT-23-5 RoHS package. It is a 5-pin device which offers a wide range of features including low noise, low supply current, and low output resistance for improved power supply regulation and circuit performance. The device is ideal for applications that require very low dropout voltage and tight output regulation such as audio amplifiers, portable audio players, and cellular phones. Additionally, it also provides protection against short-circuits, over-voltage, and current limiting. This device is designed to offer reliable protection and low voltage dropout for both positive and negative polarities, making it suitable for many applications.
