BU30TD2WNVX-TL

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

The BU30TD2WNVX-TL is a fixed positive low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 3 V output with a maximum current capacity of 200 mA. The device operates within an input voltage range of 1.7 V to 6 V and maintains a typical dropout voltage of 240 mV at full load. Key electrical specifications include a ripple rejection ratio of 70 dB, line regulation of 2 mV, and load regulation of 10 mV. Quiescent current consumption is limited to 35 uA, ensuring efficient power management. The unit features a voltage accuracy of 1% and is housed in a compact SSON004X1010-4 surface-mount package.

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

Verify the specific suffix TL indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official documentation prior to integration. Ensure the operating temperature range of -40°C to +85°C aligns with system environmental requirements. Validate that the SSON004X1010-4 footprint matches the PCB layout design constraints.

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

Select this component when a fixed 3 V rail is required with minimal noise sensitivity. The 200 mA output capability supports moderate load currents without external pass transistors. The small 1.0 mm x 1.0 mm package size is suitable for space-constrained designs. Consider the 35 uA standby current for applications requiring long-term battery operation.
