Overview
The ADPL44002ACPZN2.5-R7 is a low-dropout linear regulator manufactured by Analog Devices Inc., designed for high-voltage applications requiring precise voltage regulation. This component operates with an input voltage range from 2.7 V to 40 V and delivers a maximum output current of 200 mA. It features a fixed output voltage of 2.5 V, ensuring stable power delivery for sensitive downstream circuitry. The device exhibits a typical quiescent current of 80 uA, contributing to efficient power management in battery-operated or energy-constrained systems. With a maximum dropout voltage of 450 mV and a typical power supply rejection ratio (PSRR) of 78 dB, it maintains performance under varying load and line conditions. Operating within a temperature range of -40°C to +125°C, the regulator is housed in an LFCSP-6 package suitable for surface-mount assembly.
Feature Summary
- Provides regulated 2.5 V output from high input voltages up to 40 V
- Delivers 200 mA continuous output current with low quiescent consumption
- Ensures high noise immunity through significant power supply rejection capabilities
- Operates reliably across extended industrial temperature ranges
Applications
- High-voltage sensor biasing circuits
- Industrial control system power supplies
- Telecommunications infrastructure equipment
- Automotive electronic modules
Procurement Notes
Verify the exact part number suffix against official Analog Devices documentation to confirm the fixed 2.5 V output variant. Ensure compatibility with LFCSP-6 footprint requirements during procurement planning. Confirm RoHS compliance status through the manufacturer's latest certification records before finalizing orders.
Selection Notes
Select this component when a stable 2.5 V rail is required from inputs exceeding standard logic levels. Consider the 40 V input rating for direct connection to higher voltage buses without pre-regulation. Evaluate thermal dissipation needs based on the voltage differential between input and output at full 200 mA load.
Part Context
This part belongs to the ADPL44002 series of low-dropout regulators from Analog Devices. The series is characterized by its ability to handle high input voltages while maintaining low noise and high PSRR. The ACPZN2.5 designation specifically indicates the fixed 2.5 V output version within the LFCSP-6 package family.
Replacement Considerations
Consult Analog Devices official substitution guides for verified equivalents. Cross-reference pinouts and electrical specifications carefully if considering alternative manufacturers.
