BU30JA2DG-CTR

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

The BU30JA2DG-CTR is a single-channel, fixed-output CMOS LDO regulator manufactured by ROHM Semiconductor. It provides a 200 mA output current with a fixed voltage setting and operates within an input voltage range of 1.7 V to 6 V. The device features a typical ripple rejection ratio of 68 dB and a maximum dropout voltage of 160 mV at full load. It includes shutdown functionality, thermal shutdown protection, and over-current protection. Qualified under AEC-Q100 standards for automotive applications, it operates from -40°C to +125°C and is housed in an SSOP-5 package.
