Overview
The ADM663AAN is a precision linear voltage regulator from Analog Devices Inc., housed in an 8-pin PDIP package. It provides fixed +3.3 V or +5 V outputs, or an adjustable range via external resistors. The device features a maximum quiescent current of 9 µA and supports an output current of 100 mA. It operates with a positive polarity and includes protection against thermal overload and short-circuit conditions.
Feature Summary
- Precision regulation with low quiescent current consumption
- Configurable for fixed +3.3 V, +5 V, or adjustable output voltages
- Integrated thermal overload and short-circuit protection
Applications
- Battery-powered portable electronics requiring low standby current
- Embedded systems needing stable +5 V logic supply rails
- Industrial control modules utilizing adjustable voltage references
Procurement Notes
Verify the specific suffix 'AAN' corresponds to the 8-PDIP package and commercial/industrial temperature range as defined in the official Analog Devices datasheet. Confirm RoHS compliance status and lead-free manufacturing details directly from the manufacturer's documentation before integration into production designs.
Selection Notes
Select this component when a single-output LDO with high precision and ultra-low static current is required. It is suitable for applications where power efficiency during idle states is critical. Ensure the input voltage exceeds the dropout voltage for the desired load current and that the thermal dissipation capabilities of the PDIP package are sufficient for the operating environment.
Part Context
The ADM663A belongs to the ADM663/ADM666 family of precision linear regulators designed by Analog Devices. These devices are engineered for high accuracy and stability, often serving as reference sources or primary power supplies in sensitive analog and digital circuits. The AAN variant specifically denotes the through-hole DIP packaging option.
Replacement Considerations
Direct pin-compatible replacements within the same family include the ADM666AAN. Verify electrical specifications such as quiescent current and output tolerance match the design requirements before substituting.
