“Maxim Integrated recently announced their new series of linear regulators that maintain ±1% output accuracy over a wide operating temperature range with only 12µVrms of noise.
If you’re looking for a physically small LDO that offers low output noise and a ±1% voltage output accuracy (despite significant load, line, and temperature variations), provides configurable output voltage, and comes with many protection features, you should consider Maxim’s new MAX38902x series of LDOs. Within this new series are four regulator types to choose from (they all share the same datasheet):
- MAX38902A
- MAX38902B
- MAX38902C
- MAX38902D
Offered in Small Packages
Two of the devices from this series, namely the MAX38902A and MAX38902B, are available in a 2 × 2mm, 8-pin TDFN, or thin DFN, package. The other two devices—the MAX38902C and MAX38902D—come in a much smaller package, specifically a 2 × 3 bump, 1.22 × 0.82mm, 0.4mm pitch wafer-level package (WLP).
The figure below shows an overview of these two package types. You can find more detailed information in their app note (Application Note 1891) “Wafer-Level Packaging (WLP) and Its Applications” (PDF).”
