BU10JA2MNVX-CTL

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

The BU10JA2MNVX-CTL is a Full CMOS Low Dropout (LDO) voltage regulator manufactured by Rohm Semiconductor. It provides a fixed 1.0V output with a maximum load current of 200mA. The device operates within an input voltage range of 1.7V to 6V and features a typical circuit current of 35μA. Key electrical parameters include a typical dropout voltage of 0.8V at 200mA, a ripple rejection ratio of 70dB, and line/load regulation of 2mV/10mV respectively. It is housed in a compact SSON004R1010 package measuring 1.00mm x 1.00mm x 0.60mm. The component is AEC-Q100 qualified for automotive applications and supports a junction temperature range from -40°C to +125°C.

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

Verify the specific suffix 'CTL' against the manufacturer's official datasheet to confirm tape-and-reel packaging and pin configuration. Ensure the design accounts for the 1.0V fixed output accuracy and thermal dissipation requirements within the small footprint. Confirm AEC-Q100 qualification status matches the target automotive functional safety level before finalizing procurement.

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

Select this component when a fixed 1.0V rail is required for automotive sensors or cameras. The choice is driven by the need for minimal PCB area due to the 1x1mm package and low standby current. Compare against other series members like BUxxJA2MNVX-C only if different output voltages are needed, as the package and protection features remain consistent across the family.

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

This part belongs to the BUxxJA2MNVX-C series, marketed by Rohm as the world's smallest automotive LDO regulators. The series integrates analog design, process, and packaging technologies to achieve miniaturization for ADAS sensors and cameras. It shares the SSON004R1010 form factor with other variants offering different fixed output voltages such as 1.8V, 2.5V, and 3.3V.

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

Direct substitutes within the same series include BU18JA2MNVX-CTL (1.8V), BU25JA2MNVX-CTL (2.5V), and BU33JA2MNVX-CTL (3.3V). These parts share identical packages and protection features but differ in output voltage. Verify that the system can tolerate the alternative voltage levels before substitution.
