ABLIC Inc. S-1155 series, part S-1155B21-U5T1U, is a positive fixed output voltage linear regulator. This device offers a stable 2.1V output with a maximum current capability of 500mA. Designed for surface mount applications, it is supplied in a SOT-89-5 package via tape and reel. Key features include a low quiescent current of 1 µA and a shutdown current of 90 µA, making it suitable for power-sensitive designs. Protection mechanisms such as overcurrent and thermal shutdown are integrated. The regulator exhibits a high power supply rejection ratio (PSRR) of 65dB at 1kHz and a low dropout voltage of 0.15V at 200mA. This component finds application in consumer electronics and automotive systems.
