The ADM663A/ADM666A are precision linear voltage regulators featuring a maximum quiescent current of 9 µA. They can be used to give a fixed +3.3 V or +5 V output with no additional external components or can be adjusted from 1.3 V to 16 V using two external resistors. Fixed or adjustable operation is automatically selected via the VSET input. The low quiescent current makes these devices especially suitable for battery powered systems. The input voltage range is 2 V to 16.5 V, and an output current up to 100 mA is provided. Current limiting may be set using a single external resistor. For additional safety, an internal thermal shutdown circuit monitors the internal die temperature.

The ADM666A features additional low battery monitoring circuitry to detect for low battery voltages.

The ADM663A/ADM666A are pin compatible enhancements for the ADM663/ADM666. Improvements include an additional 3.3 V output range, higher output current, and operation with a small output capacitor.

The ADM663A/ADM666A are available in an 8-pin DIP and narrow surface mount (SOIC) packages.
