BD450M2WEFJ-CE2

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

The BD450M2WEFJ-CE2 is a low dropout (LDO) voltage regulator from ROHM Semiconductor, designed for automotive applications. It provides a fixed output of either 3.3V or 5.0V with an accuracy of ±2.0%. The device supports a maximum output current of 200mA and features a typical quiescent current of 40µA. It operates within an input voltage range of 5.5V to 42V, with a maximum withstand voltage of 45V. Key electrical parameters include a typical ripple rejection of 65dB, a typical dropout voltage of 160mV at 100mA, and load regulation of 10mV. The component is housed in an HTSOP-J8 package and is rated for junction temperatures from -40°C to +150°C.
