BU25JA2DG-CTR

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

The BU25JA2DG-CTR is a single-output, positive fixed CMOS LDO voltage regulator manufactured by ROHM Semiconductor. It provides a fixed output voltage of 2.5 V with a maximum output current of 200 mA. The device operates within an input voltage range of 1.7 V to 6 V and features a typical ripple rejection ratio of 70 dB at 1 kHz. Key electrical parameters include a maximum dropout voltage of 280 mV, line regulation of 2 mV, and load regulation of 10 mV. It is housed in a compact SSON004R1010-4 package (1.00 mm × 1.00 mm × 0.60 mm) and supports surface-mount installation. The component is qualified under AEC-Q100 standards for automotive applications.

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

Verify the specific suffix 'CTR' against the manufacturer's official datasheet to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the order quantity aligns with the standard factory pack size of 5,000 units or cut-tape availability. Confirm that the SSOP5 package variant matches the required board space constraints before finalizing procurement.

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

Select this component when a 2.5 V rail is required with up to 200 mA load capacity in automotive environments. Prioritize this part for designs needing high PSRR to minimize noise coupling into sensitive circuits. Consider the ultra-small package dimensions if board real estate is limited compared to standard SSOP5 alternatives.
