Overview
The ADP7102ACPZ-9.0-R7 is a 20 V, 300 mA low noise CMOS LDO from Analog Devices Inc. It provides a fixed 9.0 V output with an initial accuracy of ±0.8%. The device operates with an input voltage range of 3.3 V to 20 V and delivers a typical quiescent current of 750 μA at full load. Output noise is specified at 15 μV rms for fixed versions. It features reverse current protection, foldback current limit, thermal overload protection, and a power-good indicator. The regulator is stable with small 1 μF ceramic output capacitors.
Feature Summary
- Provides low noise regulation suitable for sensitive analog circuits
- Includes user-programmable precision undervoltage lockout and enable functions
- Features digital power-good status indication for system monitoring
- Offers reverse current protection and thermal overload safeguards
Applications
- Regulation for ADC and DAC circuits
- Precision amplifier power supplies
- High frequency oscillator and clock stabilization
- Phase-locked loop (PLL) power conditioning
Procurement Notes
Verify the specific suffix -R7 indicates tape and reel packaging when ordering. Confirm the ACPZ designation corresponds to the 8-lead LFCSP package type required for your PCB layout. Ensure the 9.0 V fixed output variant matches the target rail voltage. Cross-reference the manufacturer's latest datasheet revision to confirm pinout and electrical specifications remain unchanged before finalizing procurement.
Selection Notes
Select this component when a fixed 9.0 V rail is needed from inputs up to 20 V. It is appropriate for designs requiring low output noise without external filtering components. Consider the 8-lead LFCSP package for compact board space. Verify that the application load does not exceed 300 mA and that input voltage remains within the 3.3 V to 20 V operating range for optimal performance.
Part Context
This part belongs to the ADP7102 family of high input voltage low dropout regulators. The family offers multiple fixed voltage options and an adjustable version. The ACPZ suffix denotes the leadless chip scale package format. This series is designed for battery-powered portable equipment due to its low quiescent current consumption and efficient operation under varying load conditions.
Replacement Considerations
Check for direct pin-compatible substitutes within the same ADP7102 family offering different fixed voltages if the 9.0 V output is incorrect. Verify that alternative packages like SOIC meet thermal requirements. Ensure any replacement maintains the 300 mA current capability and low noise specifications required by the sensitive analog loads.
