BU35TH5WNVX-TL

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

The BU35TH5WNVX-TL is a fixed-output Low Dropout (LDO) regulator manufactured by ROHM Semiconductor. It provides a stable 3.5 V output with a maximum current capacity of 300 mA. The device features a typical ripple rejection ratio of 70 dB and operates within an input voltage range that supports a dropout voltage of 200 mV to 220 mV. It consumes only 50 µA of quiescent current. The regulator is housed in a compact DFN-4 surface-mount package and is designed for operation across a temperature range of -40°C to +85°C.

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

Verify the NRND status before integration, as this component is not recommended for new designs. Confirm the specific suffix matches the required electrical characteristics. Ensure the DFN-4 package footprint aligns with the PCB layout. Check RoHS compliance documentation for regulatory requirements. Validate the operating temperature range against the final application environment.

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

Select this LDO when a fixed 3.5 V rail is required with minimal board space. The DFN-4 package offers a small form factor suitable for dense layouts. Consider the 300 mA limit for load requirements. The low quiescent current makes it suitable for battery-operated devices. Verify that the input voltage remains within the specified limits to maintain regulation.
