BU10TD3WG-TR

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

The BU10TD3WG-TR is a fixed positive Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It belongs to the BUxxTD3WG series, featuring a standard CMOS architecture with a 200 mA maximum output current capability. The device provides a fixed 1.0 V output voltage and operates within an input voltage range of 1.7 V to 6 V. Key electrical specifications include a typical dropout voltage of 240 mV at full load, a quiescent circuit current of 35 µA, and a ripple rejection ratio of 70 dB. The unit is housed in a compact SSOP-5 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 against official ROHM documentation to confirm exact packaging configuration and revision status. Ensure compatibility with the target application's input voltage constraints and thermal dissipation requirements. Confirm that the SSOP-5 footprint matches the design layout. Check for any recent product change notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

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

Select this component when a stable 1.0 V rail is required with moderate current demands up to 200 mA. The low quiescent current makes it suitable for battery-operated devices where standby power conservation is critical. Verify that the input voltage remains above the minimum threshold while accounting for dropout voltage under maximum load conditions. Consider the thermal performance within the SSOP-5 package if ambient temperatures approach the upper operational limit.
