PRODUCT DESCRIPTION

The AS2975 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 AS2975 features very low quiescent current and very low

dropout voltage (Typ. 50mV at light load and 380 mV at 180 mA). This includes a tight initial tolerance of 0.5% typ., extremely good

load and line regulation 0.05% typ. and very low output temperature coefficient, making the AS2975 useful as a low-power voltage

reference. Other additional key features include higher output current (150mA), positive transient protection up to 60V (Load dump),

and the ability to survive an unregulated input voltage transient of -20V below ground (reverse battery).

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.

Another feature is the logic-compatible shutdown input which enables the regulator to be switched on and off. The AS2975 is offered

in a 3-pin TO-92 package compatible with other 5V regulators. The AS2975 is available in 8-pin plastic, SO-8 packages.
