BU26TA2WNVX-TR

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

The BU26TA2WNVX-TR is a single-channel, fixed-output Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed output voltage of 2.6 V with a maximum output current of 200 mA. The device operates within an input voltage range of 2.5 V to 6.5 V and features a typical dropout voltage of 400 mV at full load. Key electrical specifications include a power supply rejection ratio (PSRR) of 65 dB, line regulation of 2 mV, and load regulation of 20 mV. The quiescent current is 40 µA, and the voltage adjustment accuracy is ±1%. It is housed in an SSON004X1216 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 specific suffix TR indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SSON004X1216 footprint matches the design layout. Check for any automotive qualification restrictions as standard grade parts may not be suitable for vehicle equipment.

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

Select this component when a precise 2.6 V rail is required with low noise characteristics. The 65 dB PSRR makes it suitable for sensitive analog or RF sections. Consider the 40 µA standby current for power efficiency requirements. Verify that the input voltage remains above the minimum threshold while accounting for dropout voltage variations across the specified temperature range.
