PRODUCT DESCRIPTION
The AS1129 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 AS1129 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 AS1129 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 AS1129 is offered TO-92, SOT-223, TO-220, TO-252 and TO-263 in 3 & 5 leads.
