BU1JTD2WNVX-TL

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

The BU1JTD2WNVX-TL is a single-output, positive fixed CMOS LDO voltage regulator manufactured by ROHM Semiconductor. It provides a fixed output voltage of 1.85V with a maximum output current of 200mA. The device operates within an input voltage range of 1.7V to 6V and features a typical dropout voltage of 380mV at full load. Key electrical specifications include a quiescent current of 35µA, a ripple rejection ratio of 70dB, and a line regulation of 2mV. The unit is housed in a compact SSON004X1010-4 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 output voltage variant (1.85V) against system requirements before procurement. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature range. Ensure the input voltage does not exceed the 6V maximum limit. Check for RoHS compliance documentation if required by regulatory standards. Validate that the SSON004X1010-4 footprint matches the PCB layout design.

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

Select this component when a low quiescent current of 35µA is critical for battery life extension. Choose this model for applications requiring a fixed 1.85V rail with 200mA capability. Consider this part for designs needing high PSRR (70dB) to suppress noise in sensitive analog or RF sections. Verify that the 380mV typical dropout voltage meets the minimum headroom requirements of the specific input source.

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

This component belongs to the BU**TD2WNVX series of 200mA CMOS LDO regulators. These devices are characterized by their ultra-low current consumption and small form factor. The series is designed for general-purpose power management in portable electronics, offering a balance between performance and physical size without requiring external adjustment components.

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

BU1CTD2WNVX-TL: Offers similar 200mA performance but with a different fixed output voltage (1.25V). BU13TD2WNVX-TL: Similar package and current rating but outputs 1.3V. BU20TD2WNVX-TL: Similar package and current rating but outputs 2.0V. Substitution requires verifying that the alternative output voltage matches the target circuit's power rail requirements.
