PRODUCT DESCRIPTION
The AS1121 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 AS1121 features very low quiescent current and very low
dropout voltage of 0.4 volts. This includes a tight initial tolerance of
±
1% max, and very low output temperature coefficient, making
the AS1121 useful as a low-power voltage reference.
The error flag output feature is used as power-on reset for warning of a low output voltage, due to falling voltage input of batteries.
The AS1121 is offered SO-8, TO-92 & SOT-223.
