BU25JA2VG-CGTR

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

The BU25JA2VG-CGTR is a single-channel CMOS LDO regulator from ROHM Semiconductor, designed for automotive applications. It provides a fixed 2.5V output with a maximum current of 300mA. The device operates within an input voltage range of 1.7V to 6V and withstands up to 6.5V. Key electrical parameters include a typical dropout voltage of 240mV at 100mA, a quiescent current of 4µA, and a ripple rejection ratio of 60dB at 1kHz. Line regulation is 4mV, and load regulation is 15mV. It features AEC-Q100 qualification and operates between -40°C and +150°C in an SSOP-5 package.

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

Verify the complete part number including the suffix CGTR to ensure correct packaging and tape-and-reel configuration. Confirm that the fixed 2.5V output matches the target circuit requirements. Check for RoHS compliance status and functional safety classification if required by the specific automotive application standard.

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

Select this component when a low-noise, high-current LDO is needed for automotive environments. The 300mA output capacity supports moderate load demands. Ensure the input voltage remains above 1.7V and below 6V. The wide operating temperature range up to 150°C suits harsh under-hood conditions.

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

This part belongs to the BU25JA series of full CMOS LDO regulators optimized for automotive use. It shares the SSOP-5 footprint with other variants in the family but differs in output voltage and current ratings. The series is characterized by low standby current and high ripple rejection ratios suitable for sensitive analog circuits.

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

Direct pin-compatible substitutes within the same series include BU25JA1VG-CGTR (1.8V) and BU25JA3DG-CTR (3.3V). Verify that the replacement maintains the 300mA output capability and AEC-Q100 qualification level.
