BD433M2FP3-CE2

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

The BD433M2FP3-CE2 is a positive low dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed 3.3V output with a maximum current of 200mA. The device operates within an input voltage range of 3.9V to 42V and features a typical dropout voltage of 200mV at 100mA load. Key electrical specifications include a quiescent current of 40µA, ripple rejection of 65dB, and line regulation of 10mV. It is housed in an SOT-223-4F package and supports junction temperatures from -40°C to +150°C.
