Key Features
- Ultralow 9 µVRMS output noise enabling clean supply rails for noise-sensitive RF and analog circuits
- Only 105 mV typical dropout voltage at 150 mA, maximizing efficiency in battery-powered designs
- Compact 4-ball WLCSP package (0.73 mm x 0.73 mm) ideal for space-constrained wearable and IoT applications
- Wide 2.2 V to 5.5 V input range supporting single-cell Li-Ion and regulated 5 V system rails
Applications
The ADP150ACBZ-2.8-R7 is designed for RF transceivers, PLLs, and precision ADCs where supply noise directly degrades signal quality, making its 9 µVRMS noise floor a key differentiator. It fits compactly into wearable medical devices, wireless sensor nodes, and smartphone camera modules that run from single-cell Li-Ion batteries between 2.7 V and 4.2 V. Its 150 mA current capability and low dropout also suit post-regulation stages in portable audio and GPS receivers demanding a stable 2.8 V rail.

Frequently Asked Questions
How low is the output noise of ADP150ACBZ-2.8-R7, and why does that matter for RF receiver designs?
The ADP150ACBZ-2.8-R7 produces only 9 µVRMS integrated output noise from 10 Hz to 100 kHz. For an RF LNA or PLL running at 2.8 V, supply noise couples directly into phase noise and receiver sensitivity; a 9 µVRMS rail keeps this coupling below the thermal noise floor of most sub-GHz and 2.4 GHz front-end circuits.
What is the dropout voltage of ADP150ACBZ-2.8-R7 at full load, and how does it affect battery runtime?
At 150 mA output current, the typical dropout voltage is 105 mV, meaning the device regulates correctly when the input is as low as 2.905 V. For a single-cell Li-Ion battery discharging from 4.2 V down to about 3.0 V, the regulator stays in regulation for nearly the full discharge cycle, extending usable battery runtime compared to regulators requiring 300 mV or more of headroom.
Can ADP150ACBZ-2.8-R7 supply a 2.8 V image sensor module from a 3.3 V system rail?
Yes. With a 3.3 V input and a 2.8 V fixed output, the headroom is 500 mV — well above the 105 mV typical dropout. At up to 150 mA load the device remains in full regulation, delivering a stable 2.8 V ± 2% (56 mV) tolerance suitable for CMOS image sensor analog power rails that typically require ±5% or better regulation.
How small is the ADP150ACBZ-2.8-R7 package, and what PCB clearance is needed for hand-soldering assembly?
The ADP150ACBZ-2.8-R7 uses a 4-ball WLCSP measuring approximately 0.73 mm x 0.73 mm with a 0.4 mm ball pitch. This sub-millimeter footprint requires reflow soldering rather than hand soldering; automated SMT placement with Type 4 or finer solder paste is recommended, and X-ray inspection is advisable to verify joint integrity under the 4 solder balls.
