Overview
The ADPL42001ATT+T is a high-voltage linear regulator featuring ultra-low quiescent current, designed for industrial and battery-powered systems. It operates with an input voltage range of 4V to 20V and delivers up to 100mA load current. The device offers adjustable output voltage from 0.6V to 18V with ±2% feedback voltage accuracy across the temperature range. Quiescent current is 8μA in normal operation and drops to 0.9μA in shutdown mode. It includes a power-good signal via an open-drain PGOOD pin and thermal shutdown protection at +165°C.
Feature Summary
- Ultra-low static current consumption for extended battery life
- Integrated power-good monitoring with open-drain output
- High-voltage enable input for system control
- Compact design requiring only four external components
Applications
- Battery-powered equipment
- Post-regulators for switching power supplies
- Automotive body electronics and lighting
Procurement Notes
Verify the specific suffix ATT+T against official Analog Devices documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with required operating temperatures and input voltage ranges before integration. Cross-reference datasheet revisions for any updates to electrical characteristics or pinout definitions.
Selection Notes
Select this component when low quiescent current is critical for standby power efficiency in high-voltage applications. The adjustable output range allows flexibility for various rail requirements. Consider the compact TSOT or TDFN packages for space-constrained designs requiring full ceramic capacitor stability.
Part Context
This part belongs to the ADPL series of high-voltage linear regulators from Analog Devices/Maxim Integrated. The series is characterized by low noise and high PSRR, suitable for sensitive analog circuits. The ADPL42001 specifically targets industrial environments with its wide operating temperature range and robust protection features.
Replacement Considerations
Check for direct substitutes within the ADPL family such as ADPL42002 or ADPL42005 if different current ratings are needed. Verify pin-to-pin compatibility and electrical parameter overlaps before substitution.
