BU27TA2WNVX-TR

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

The BU27TA2WNVX-TR is a fixed-output CMOS LDO regulator manufactured by ROHM Semiconductor. It provides a 2.7V output with a maximum current of 200mA in an SSON004X1216 package. The device operates within an input voltage range of 2.5V to 5.5V and features a typical dropout voltage of 360mV at full load. Key electrical parameters include a ripple rejection ratio of 65dB, quiescent current of 40µA, and voltage accuracy of ±1.0%. It supports operation from -40°C to +85°C and includes shutdown, thermal shutdown, and overcurrent protection.

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

Verify the specific suffix TR indicates tape and reel packaging when ordering. Confirm the exact output voltage of 2.7V matches the design requirement, as other variants in the series offer different voltages. Check RoHS compliance status and ensure the SSON004X1216 footprint aligns with the PCB layout. Validate that the operating temperature range meets the environmental conditions of the target application.

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 200mA output capability suits moderate load requirements. Compare against the BU27TD2WNVX-TL if a smaller SSON004X1010-4 package or lower dropout voltage is preferred. Ensure the input voltage remains above the minimum threshold of 2.5V for proper regulation.
