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

Verify the specific suffix against official ROHM documentation to confirm exact tape-and-reel specifications and marking codes. Ensure the procurement channel provides valid RoHS compliance certificates. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature range. Note that this component is not recommended for automotive use according to manufacturer guidelines.

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

Select this regulator when a stable 2.6 V rail is required from a low-voltage source with minimal quiescent drain. The HVSOF5 package is ideal for portable devices where board space is limited. Consider the 0.28 V dropout voltage to ensure sufficient headroom between input and output under maximum load conditions. Verify that the external capacitor value meets the stability requirements for the specified output current.

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

This component belongs to the BU27TA2WHFV/HFV series of high-performance full CMOS regulators. These devices are engineered for low-noise applications requiring small form factors. The series utilizes advanced CMOS technology to achieve high ripple rejection while maintaining extremely low standby currents, making them distinct from standard bipolar LDOs in efficiency and noise performance profiles.

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

Check ROHM datasheets for other fixed-output variants within the same series, such as BU29TA2WHFV or BU18TA2WHFV, which share identical pinouts and package dimensions but offer different voltage levels. Ensure any substitute maintains the same HVSOF5 footprint and electrical characteristics regarding dropout voltage and current limits.
