BD30IA5MEFJ-LBH2

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

The BD30IA5MEFJ-LBH2 is a low-dropout (LDO) linear voltage regulator manufactured by ROHM Semiconductor. It provides a fixed positive output voltage of 3.0 V with a maximum output current capability of 500 mA. The device features high accuracy, maintaining an output voltage tolerance of ±1.0% at 25°C ambient temperature. It operates within an input voltage range from a minimum of 2.4 V to a maximum of 5.5 V. The typical dropout voltage is 0.4 V when delivering the full 0.5 A load. The circuit draws a quiescent current of approximately 0.25 mA. It includes built-in protection mechanisms such as over-current protection and thermal shutdown circuits to prevent damage during fault conditions.
