BU18TA2WNVX-TR

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

The BU18TA2WNVX-TR is a single-channel, fixed-output low-dropout linear regulator manufactured by ROHM Semiconductor. It provides a stable 1.8V output with a maximum current capacity of 200mA. The device operates within an input voltage range of 2.5V to 5.5V and supports a maximum withstand voltage of 6.5V. Key electrical specifications include a typical ripple rejection ratio of 70dB at 1kHz, a quiescent circuit current of 40µA, and a load regulation of 10mV across the specified current range. The unit features ±25mV output accuracy at 25°C and utilizes an SSON004X1216 package.

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

Verify the specific suffix TR indicates tape and reel packaging configuration when sourcing. Confirm RoHS compliance status matches project environmental requirements. Ensure the selected distributor provides official datasheets to validate the 1.8V fixed output and 200mA rating against design specifications before finalizing procurement orders.

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

Select this component for applications requiring a compact form factor and low standby current. The 1.8V output is appropriate for standard logic families. Verify that the input voltage remains above the minimum threshold of 2.5V to ensure proper regulation. Consider the thermal dissipation capabilities given the small package size when designing for high ambient temperatures or continuous full-load operation.
