Overview
The ADP7112ACBZ-5.0-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc., featuring a fixed 5.0 V output and a maximum load current of 200 mA. It operates within an input voltage range of 2.7 V to 20 V, delivering high power supply rejection ratios of 88 dB at 10 kHz and 68 dB at 100 kHz. The device exhibits low noise performance with an RMS output noise of 11 μV across the 10 Hz to 100 kHz bandwidth. Initial output voltage accuracy is specified at ±0.8%, expanding to ±1.8% over the full operating temperature range of −40°C to +125°C. Quiescent current consumption is typically 50 μA under no-load conditions, while shutdown current drops to approximately 3.0 μA at 20 V input.
Feature Summary
- Provides ultra-low output noise of 11 μV rms independent of fixed output voltage options
- Features user-programmable soft start capability controlled by an external capacitor
- Includes precision enable logic with adjustable thresholds for system power sequencing
- Maintains stability using small 2.2 μF ceramic output capacitors
Applications
- Regulation for noise-sensitive analog-to-digital and digital-to-analog converter circuits
- Power supply for precision amplifiers and voltage-controlled oscillator tuning nodes
- Infrastructure and communications equipment requiring clean DC rails
- Medical and healthcare instrumentation systems
Procurement Notes
Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm that the specific ordering suffix matches the required package type and output voltage configuration. Ensure all environmental compliance documentation aligns with project specifications prior to final procurement authorization.
Selection Notes
Evaluate thermal dissipation requirements based on the difference between input and output voltages combined with the maximum load current. Verify that the selected input and output capacitors meet the minimum capacitance and effective series resistance specifications to ensure loop stability. Consider the programmable enable threshold if precise power sequencing relative to other system rails is required.
Part Context
This component belongs to the ADP7112 family of high-performance LDO regulators designed for applications demanding low noise and wide input voltage ranges. The family supports various fixed output voltages and includes an adjustable variant. The WLCSP packaging provides a compact footprint suitable for space-constrained portable and industrial designs.
Replacement Considerations
Consult official Analog Devices documentation for verified cross-reference part numbers. Ensure any substitute maintains identical pinout configurations, electrical characteristics, and package dimensions to guarantee mechanical and functional compatibility without redesigning the host circuit board.
