Description
The Bay Linear B1121 is a low power voltage regulator.
This device is an excellent choice for use in battery powered applications such as cordless telephones, radio control systems, and portable computers. The B1121 features very low quiescent current and very low dropout voltage of 0.40 volts. This includes a tight initial tolerance of ± 1% max, and very low output temperature coefficient, making the B1121 useful as a low-power voltage reference.
