Key Features
- Integrated under-voltage and over-voltage fault alert with programmable delay, eliminating the need for a separate voltage supervisor IC in sensitive supply rails
- Adjustable output voltage LDO delivering up to 400 mA with 2 V reference, covering a wide range of point-of-load regulation needs
- 16-pin SOIC package with plastic/epoxy construction for cost-effective surface-mount assembly in industrial and communications power management designs
Applications
The UC2832DWG4 is used in point-of-load linear regulation for DSP, FPGA, and microcontroller power supplies where both voltage regulation and supply supervision are required. Its programmable fault alert outputs allow system controllers to detect out-of-range conditions and initiate safe shutdown or fault logging before downstream circuits are damaged. The device is also used in communication infrastructure cards and industrial control modules where power rail integrity monitoring is critical.

Frequently Asked Questions
What is the maximum output current of the UC2832DWG4?
The UC2832DWG4 can supply up to 400 mA of continuous output current. This makes it suitable for powering low-power digital logic, analog circuitry, and mixed-signal devices in point-of-load regulation applications where an LDO regulator is preferred over a switching converter.
What fault detection features does the UC2832DWG4 provide?
The UC2832DWG4 includes integrated under-voltage and over-voltage fault alert outputs with a programmable delay. The programmable delay allows designers to filter out short transients and avoid spurious fault triggers, improving system reliability in noisy power environments.
What is the reference voltage of the UC2832DWG4?
The UC2832DWG4 uses a 2 V internal reference voltage. The output voltage is adjustable via external resistor divider, allowing the designer to set the regulated output to any voltage above the LDO dropout level, making it versatile for various supply rail requirements.
What package does the UC2832DWG4 come in?
The UC2832DWG4 is supplied in a 16-pin SOIC package (JESD-30 code R-PDSO-G16) with plastic/epoxy construction. The SOIC footprint is standard across PCB assembly equipment and is compatible with automated pick-and-place and reflow soldering processes.
