BU26UA3WNVX-TL

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The BU26UA3WNVX-TL is a single-output low-dropout (LDO) linear regulator manufactured by ROHM Semiconductor. It operates within an input voltage range of 1.7 V to 6 V and provides a fixed output voltage of 2.6 V with a maximum output current of 200 mA. The device features a typical power supply rejection ratio (PSRR) of 70 dB and a typical dropout voltage of 280 mV at full load. It maintains a line regulation of 2 mV and load regulation of 10 mV, with a quiescent current of 35 uA. The unit is housed in a DFN-4 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the Not Recommended for New Design (NRND) status before finalizing any procurement plans. Confirm that the DFN-4 package dimensions align with existing PCB footprints. Ensure the 2.6 V fixed output meets system requirements as no adjustable variants exist in this specific part number. Check for RoHS compliance documentation if required by local regulations.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a compact 200 mA LDO with a 2.6 V fixed output is required for space-constrained designs. The DFN-4 package offers a small footprint suitable for portable electronics. Consider the 35 uA quiescent current for battery-powered applications. Verify that the 6 V maximum input voltage accommodates the highest expected supply rail without exceeding limits.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This component belongs to the BU26UA3WNVX series of CMOS LDO regulators. It shares the same physical package and general performance characteristics with other voltage variants in the family, such as the BU18UA3WNVX-TL and BU19UA3WNVX-TL. The primary distinction lies in the fixed internal reference voltage setting the output level.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

BU26TD2WNVX-TL: Offers identical 2.6 V output and 200 mA current but utilizes an SSON004X1010 package instead of DFN-4. Verify mechanical compatibility before substitution.
