Overview
The ADPL44001ATT+ is a low-dropout (LDO) linear voltage regulator manufactured by Analog Devices Inc. under the Maxim Integrated brand. It is designed to provide a stable output with an input voltage range of 4 V to 40 V and supports up to 100 mA of load current. The device features ultra-low quiescent current consumption, making it suitable for battery-powered applications. It operates within a temperature range of -40°C to +125°C and is available in a compact SOT-23-5 package.
Feature Summary
- Ultra-low quiescent current consumption for extended battery life
- Wide input voltage range supporting 4 V to 40 V operation
- Integrated thermal shutdown and reverse current protection
- Compact surface-mount packaging for space-constrained designs
Applications
- Battery-powered portable electronic devices
- Industrial sensor nodes requiring low standby power
- Automotive electronics operating in harsh thermal environments
- Wireless communication modules needing stable voltage regulation
Procurement Notes
Verify the exact suffix ATT+ against official Analog Devices documentation to confirm tape-and-reel packaging and specific temperature grade. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Ensure the ordering part number matches the required package variant and lead-free specifications before finalizing procurement.
Selection Notes
Select this component when designing systems that require high input voltage tolerance combined with minimal static power draw. Evaluate the thermal performance under maximum load conditions to ensure adequate heat dissipation in the chosen enclosure. Compare dropout voltage characteristics against the minimum required headroom for the target application voltage.
Part Context
This LDO belongs to the ADPL4400x family of ultra-low quiescent current regulators. The series is engineered for applications demanding high efficiency and wide input voltage ranges. It complements other Maxim Integrated power management solutions by providing reliable linear regulation where switching noise must be minimized.
Replacement Considerations
Consult official cross-reference guides for pin-compatible alternatives. Verify that any substitute maintains the same input voltage range, current capability, and quiescent current specifications. Ensure thermal resistance and package dimensions match the existing board layout constraints.
