Overview
The ADPL42005ACPZ-1.5-R7 is a single-channel low-dropout linear regulator (LDO) manufactured by Analog Devices Inc., designed for high-performance analog and mixed-signal circuits. It operates within an input voltage range of 4V to 20V and provides a fixed output voltage of 1.5V with a maximum output current of 500mA. The device features a low dropout voltage of 400mV at full load, ensuring efficient power regulation. It includes integrated protection mechanisms such as reverse current protection, foldback current limiting, and thermal overload protection. The component utilizes an 8-lead LFCSP package.
Feature Summary
- Provides stable 1.5V output with 500mA capacity for sensitive analog loads
- Features low noise performance suitable for precision signal processing applications
- Includes comprehensive protection against reverse current, overcurrent, and thermal stress
Applications
- Powering ADC and DAC circuits requiring low noise
- Supplying precision amplifiers in instrumentation systems
- Providing clean power for high-frequency oscillators and clock circuits
Procurement Notes
Verify the specific suffix 'R7' indicates tape-and-reel packaging when ordering. Confirm the 'A' prefix denotes the commercial temperature grade variant. Ensure the 1.5V fixed output matches the system requirement, as other voltage options exist within the ADPL42005 family. Cross-reference the manufacturer part number with official distributor catalogs to confirm availability and authenticity before purchase.
Selection Notes
Select this component when a fixed 1.5V rail is required from a 4V to 20V input source. It is appropriate for designs needing 500mA drive capability with minimal quiescent current. Consider the 8-lead LFCSP package size for PCB layout constraints. This regulator is preferred over adjustable versions when a precise, unchanging voltage reference is necessary without external feedback resistors.
Part Context
This part belongs to the ADPL42005 series of CMOS LDO regulators from Analog Devices. The series is engineered for applications demanding high power supply rejection ratio (PSRR) and low output noise. The ADPL42005ACPZ-1.5-R7 specifically offers a fixed 1.5V output, distinguishing it from adjustable or other fixed-voltage variants like 3.3V or 5.0V models within the same product line.
Replacement Considerations
Direct replacements include other ADPL42005 variants with different fixed output voltages if the voltage level can be adjusted via external circuitry, though this requires redesign. Verify pin compatibility with the 8-lead LFCSP package. No direct cross-brand equivalents are confirmed in public documentation.
