Overview
The ADP7118ACPZN-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7 V to 20 V and provides up to 200 mA of output current. The device features a typical quiescent current of 50 µA at no load and a shutdown current of 1.8 µA. It delivers an output noise of 11 µV rms and achieves a power supply rejection ratio of 88 dB at 10 kHz. The unit is housed in a 6-lead LFCSP package.
Feature Summary
- Provides ultralow output noise independent of fixed output voltage options
- Features high power supply rejection across multiple frequency bands
- Includes user-programmable soft start capability via external capacitor
- Supports precision enable with programmable logic thresholds
Applications
- Regulation for noise-sensitive analog circuits
- Powering ADC and DAC circuits
- Precision amplifier biasing
- VCO VTUNE control power supplies
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing components. Confirm the ACPZN designation corresponds to the 6-lead LFCSP package variant. Ensure compatibility with the required output voltage configuration, as this part number represents a specific fixed or adjustable option within the broader ADP7118 family.
Selection Notes
Select this component for applications requiring high input voltages up to 20 V with low noise performance. Consider the 2.2 µF ceramic output capacitor requirement for stability. Evaluate thermal dissipation capabilities based on the junction-to-ambient resistance of the LFCSP package under maximum load conditions.
Part Context
This regulator belongs to the ADP7118 series from Analog Devices, designed for high-performance mixed-signal circuits. The series offers various fixed voltage options and adjustable configurations. It is supported by the ADIsimPower design tool for schematic generation and performance optimization.
Replacement Considerations
Direct substitutes include other ADP7118 variants with different output voltages or packages. Verify pinout compatibility and electrical specifications before substitution.
FAQ
Can the fixed output voltage be adjusted higher?
Yes, any fixed output voltage can be set to a higher value using an external resistor divider connected to the SENSE/ADJ pin.
What is the minimum recommended output capacitance?
A minimum of 2.2 µF ceramic capacitor with an ESR of 0.3 Ω or less is recommended for stability.
