What are the key features of UCC384DP-ADJ?
- Adjustable negative output voltage from -1.25 V to -15 V with ±2.5% output accuracy for flexible power rail design
- Low 0.25 V typical dropout voltage at 500 mA output current, minimizing power dissipation in space-constrained applications
- 8-pin SOIC package with 0.008 %/V line regulation for stable negative supply rails in analog and mixed-signal circuits
What is UCC384DP-ADJ used for?
UCC384DP-ADJ is commonly used in analog signal-processing boards, op-amp bias supplies, and audio amplifier circuits that require a clean, adjustable negative voltage rail. It is also used in test and measurement equipment where a regulated negative supply between -1.25 V and -15 V must be generated from a common negative input rail with minimal dropout loss.

Frequently Asked Questions
What output current can the UCC384DP-ADJ deliver and what is the typical dropout voltage at that load?
The UCC384DP-ADJ delivers up to 500 mA continuous output current with a typical dropout voltage of only 0.25 V and a maximum dropout of 0.5 V. This low dropout characteristic reduces power dissipation and allows operation even when the input-to-output voltage difference is small, which is critical in negative-rail supply designs.
How is the output voltage of UCC384DP-ADJ set, and what range of negative voltages can it regulate?
The output voltage is set by two external resistors connected to the ADJ pin, following the standard adjustable LDO equation. The UCC384DP-ADJ covers an adjustable range from -1.25 V to -15 V with ±2.5% accuracy, giving designers flexibility to create any negative rail within that range using standard 1% resistors.
In which circuit types is a negative LDO like UCC384DP-ADJ a better alternative to a switching negative regulator?
For noise-sensitive analog circuits such as precision ADC reference supplies, instrumentation amplifier bias, and audio pre-amplifier stages, the UCC384DP-ADJ is preferred over switching regulators because it produces no switching noise or EMI. Its 0.008 %/V line regulation ensures stable output even when the input voltage fluctuates, protecting downstream analog components.
