BD30FC0WEFJ-E2

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

The BD30FC0WEFJ-E2 is a high-accuracy linear low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed positive output voltage of 3.0 V with a maximum continuous output current of 1 A. The device operates within an input voltage range of 4.5 V to 14 V and features a typical dropout voltage of 0.6 V at full load. Key electrical specifications include a quiescent supply current of 600 uA, a load regulation of 1.5%, and a ripple rejection ratio of 60 dB. It is housed in an HTSOP-J8 surface-mount package and supports operation temperatures from -25°C to +85°C.
