Overview
The ADM663AN is a precision micropower voltage regulator manufactured by Analog Devices Inc. It provides a fixed +5V output with an adjustable mode capability ranging from 1.3V to 16V. The device operates within an input voltage range of 2V to 16.5V and delivers up to 40mA of output current. Key electrical characteristics include a maximum dropout voltage of 900mV, a quiescent current of 12µA, and a line regulation of 0.35%/V. It utilizes a PDIP-8 package for through-hole mounting.
Feature Summary
- Dual-mode operation supporting both fixed +5V and programmable voltage outputs
- Micropower design featuring low quiescent current consumption
- Precision regulation with specified line regulation performance
Applications
- Battery-powered portable equipment requiring low standby current
- Microprocessor power supply systems
- General-purpose linear regulation in industrial instrumentation
Procurement Notes
Verify the specific suffix 'AN' against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with required PCB footprint for PDIP-8 through-hole mounting. Confirm RoHS compliance status via the manufacturer's current datasheet before procurement.
Selection Notes
Select this component when a stable +5V rail or adjustable voltage between 1.3V and 16V is needed with minimal static power draw. Consider the 40mA output limit and 900mV dropout voltage for headroom calculations. Verify that the PDIP-8 package fits the assembly constraints compared to surface-mount alternatives.
Part Context
The ADM663AN belongs to the MAX663/MAX666 family of micropower regulators. These devices are designed for applications where battery life is critical due to their low quiescent current specifications. The family typically includes variants with different output voltages and packages, serving as standard solutions for low-power linear regulation tasks.
Replacement Considerations
Check for direct cross-references such as the MAX663CPA+ or other ADM663 variants with compatible pinouts and electrical parameters. Ensure any substitute maintains the same PDIP-8 package and voltage specifications.
