BD450M5WFP2-CZE2

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

The BD450M5WFP2-CZE2 is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 5 V output with a maximum continuous current of 500 mA. The device operates within an input voltage range of 3 V to 42 V and features a typical dropout voltage of 250 mV, with a maximum of 750 mV. Quiescent current is specified at 40 uA, while operating supply current is 38 uA. It offers a typical power supply rejection ratio (PSRR) of 60 dB. Line regulation and load regulation are both rated at 10 mV. The component is housed in a TO-263-5 surface-mount package and supports an operating junction temperature range from -40°C to +150°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the complete part number including suffixes such as CZE2 against official ROHM documentation to ensure correct packaging and tape specifications. Confirm AEC-Q100 qualification status if automotive reliability is required. Check RoHS and REACH compliance details via the manufacturer's datasheet before finalizing procurement orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 5 V output is required with up to 500 mA load capacity. Ensure the input voltage does not exceed 42 V and consider the 250 mV typical dropout for headroom calculations. Choose this LDO for applications demanding low static current and robust protection features like thermal shutdown and over-current limiting in automotive or industrial settings.
