Overview
The ADP7118WAUJZ-1.8-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc., providing a fixed 1.8 V output with a maximum current of 200 mA. It operates within an input voltage range of 2.7 V to 20 V and features ultralow noise of 11 µV rms. The device includes precision enable, programmable soft start, and protection against overcurrent and thermal overload. It is housed in a TSOT-23-5 package.
Feature Summary
- Ultralow output noise of 11 µV rms independent of the fixed output voltage for options up to 5 V.
- High power supply rejection ratio (PSRR) reaching 88 dB at 10 kHz.
- Precision enable pin with user-programmable thresholds and hysteresis.
- Stable operation with small 2.2 µF ceramic output capacitors.
Applications
- Regulation for noise-sensitive applications
- ADC and DAC circuits
- Power for VCO VTUNE control
Procurement Notes
Verify the specific suffix 'W' against official documentation to confirm its exact meaning regarding temperature or qualification status. Confirm the package type matches the required footprint. Ensure the ordering code corresponds to the correct reel quantity and tape specifications provided by the manufacturer.
Selection Notes
Select this component when a stable 1.8 V rail is required from inputs up to 20 V. It is suitable for portable equipment due to low quiescent current. Consider the TSOT-23-5 package for space-constrained designs. Verify that the load current does not exceed 200 mA and that the input voltage remains above 2.7 V.
Part Context
This part belongs to the ADP7118 family of low noise LDO regulators. The series offers various fixed output voltages and adjustable options. It is designed for high-performance analog and mixed-signal circuits requiring clean power supplies with excellent transient response and low dropout characteristics.
Replacement Considerations
Consult the official datasheet for direct replacements. Other packages in the same family include LFCSP and SOIC variants. Ensure any substitute maintains the 200 mA output capability and 1.8 V fixed output specification.
