Overview
The ADP7112ACBZ-3.3-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc. It operates from an input voltage range of 2.7 V to 20 V and provides up to 200 mA of output current. The device features a fixed 3.3 V output with an initial accuracy of ±0.8%. It delivers low noise performance of 11 μV rms and high power supply rejection ratios, reaching 88 dB at 10 kHz. The quiescent current is typically 50 μA with no load, dropping to 1.8 μA in shutdown mode. It utilizes a 6-ball WLCSP package measuring 1 mm × 1.2 mm.
Feature Summary
- Provides ultra-low output noise of 11 μV rms across all fixed voltage options
- Features user-programmable soft start controlled by an external capacitor
- Includes precision enable pin with adjustable logic thresholds for system control
- Stable with small 2.2 μF ceramic output capacitors
Applications
- ADC and DAC circuits requiring clean power rails
- Precision amplifiers and analog signal conditioning
- Power supplies for VCO VTUNE control
- Medical and healthcare instrumentation systems
Procurement Notes
Verify the specific suffix -R7 indicates reel packaging when sourcing. Confirm the ACBZ designation matches the required temperature grade and package variant. Ensure the ordering code corresponds exactly to the 3.3 V fixed output version. Cross-reference the manufacturer part number with official distributor catalogs to avoid counterfeit components.
Selection Notes
Select this component for applications requiring high PSRR and minimal noise in mixed-signal environments. The wide input voltage range supports conversion from higher bus voltages down to 3.3 V. Consider the thermal resistance of the WLCSP package for heat dissipation calculations under maximum load conditions.
Part Context
This part belongs to the ADP7112 family of low noise LDO regulators. The series offers multiple fixed output voltages ranging from 1.2 V to 5.0 V. All variants share the same compact 6-ball WLCSP footprint and core architectural features, differing primarily in their internal feedback resistor networks.
Replacement Considerations
Direct substitutes within the same family include other fixed voltage variants such as ADP7112ACBZ-1.8-R7 or ADP7112ACBZ-5.0-R7 if the output voltage requirement changes.
