UP0104S Datasheet — Detailed Overview

: The "S" variant (uP0104S) is noted for its design that minimizes parasitic capacitance Up0104s Datasheet

• Dropout Voltage ($V_drop$): Typically 1.2V at full load current. This allows the regulator to function effectively even when the battery voltage is nearing the required output level.
• Output Current: Capable of supplying up to 1A (depending on package thermal dissipation capabilities).
• Quiescent Current ($I_q$): Typically 5mA to 8mA. This is the current consumed by the regulator itself when no load is present.
• Line Regulation: Typically 0.1% / V. This measures the ability of the regulator to maintain constant output voltage despite changes in input voltage.
• Ripple Rejection: Approximately 60dB at 120Hz. This high rejection ratio makes it suitable for filtering noise from switching power supplies.

Worldway Electronics provides part details and inventory status. Dropout Voltage ($V_drop$): Typically 1

Example: For 1.8V (DDR VDDQ), use Rtop = 2kΩ, Rbottom = 1kΩ. use Rtop = 2kΩ

5. How to Use the UP0104S in a Design

Pro-Tip:

💡 Always verify the "Marking Code" on the physical chip, as these small SOP-8 packages can sometimes share similar physical appearances with other uPI regulators.
