BU27TA2WHFV-TR

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

The BU27TA2WHFV-TR is a single-channel CMOS LDO regulator from ROHM Semiconductor, housed in an HVSOF5 package. It delivers a maximum output current of 0.2 A with a fixed output voltage accuracy of ±1.0% at 25°C. The device operates within an input voltage range of 2.5 V to 5.5 V and withstands up to 6.5 V. Key electrical parameters include a typical dropout voltage of 0.36 V at full load, a circuit current of 40 μA, and a ripple rejection of 65 dB. Load regulation is specified at 10 mV for currents between 0.01 mA and 100 mA. Integrated protections include thermal shutdown, over-current protection, and a discharge function.

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

Verify the specific suffix (e.g., -TR) to confirm taping packaging requirements. Confirm RoHS compliance status as indicated in official documentation. Ensure the application environment remains within the standard operating temperature range of -40°C to 85°C. Do not utilize this component in automotive equipment due to explicit manufacturer restrictions regarding vehicle-mounted devices.

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

Select this regulator when low quiescent current and small form factor are critical constraints. The HVSOF5 package offers a minimal footprint compared to larger SOIC options. Verify that the required output voltage falls within the fixed variants available in the TA2 series. Ensure the load current does not exceed the 200 mA limit while maintaining adequate headroom above the dropout voltage.
