Overview
The ADP7118ACPZN5.0-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 5.0 V output with an initial accuracy of ±0.8%. It delivers ultralow noise of 11 µV rms and high power supply rejection ratios of 88 dB at 10 kHz, 68 dB at 100 kHz, and 50 dB at 1 MHz. The typical quiescent current is 50 µA with no load, and the shutdown current is 1.8 µA at VIN = 5 V. The device is housed in a 6-lead LFCSP package.
Feature Summary
- Ultralow output noise of 11 µV rms independent of fixed output voltage
- High power supply rejection ratio of 88 dB at 10 kHz
- Low dropout voltage of 200 mV typical at 200 mA load
- User programmable soft start capability via external capacitor
Applications
- Regulation for noise-sensitive applications
- ADC and DAC circuits
- Precision amplifiers
- Power for VCO VTUNE control
- Communications and infrastructure systems
Procurement Notes
Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the fixed 5.0 V output option aligns with system requirements before procurement. Ensure compatibility with the 6-lead LFCSP footprint during PCB layout planning. Check for any automotive qualification requirements if applicable to the end application.
Selection Notes
Select this component when low noise and high PSRR are critical for analog signal integrity. The 200 mA output current capability supports moderate load demands. Consider the 2.2 µF ceramic output capacitor requirement for stability. Evaluate thermal performance based on the expected power dissipation and PCB layout constraints.
Part Context
This part belongs to the ADP7118 family of low noise CMOS LDO regulators. The family offers various fixed output voltages ranging from 1.2 V to 5.0 V. It is designed for portable equipment due to its low quiescent current. The device is supported by the ADIsimPower design tool for schematic generation and performance calculation.
Replacement Considerations
Direct replacements within the same family include other fixed voltage options such as ADP7118ACPZN3.3-R7 or ADP7118ACPZN2.5-R7. Adjustable versions like ADP7118ACPZN-R7 allow for custom voltage settings. Cross-family comparisons should consider package dimensions and pinout compatibility.
