BD12KA5WFP-E2

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

The BD12KA5WFP-E2 is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 1.2 V output with a maximum load current of 500 mA. The device operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 120 mV at 0.2 A, with a maximum of 200 mV. It offers high ripple rejection of 50 dB and maintains a voltage regulation accuracy of ±1%. The component is housed in a TO-252-5 surface-mount package and supports an operating temperature range from -40°C to +105°C.

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

Verify the complete part number including the suffix E2 for lead-free compliance. Confirm the TO-252-5 package type matches your PCB footprint requirements. Ensure the fixed 1.2 V output aligns with your system design needs. Check RoHS status documentation for regulatory compliance before procurement.

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

Select this component when a fixed 1.2 V rail is required with 500 mA capability. The low dropout characteristic suits applications with narrow input-to-output voltage differentials. The integrated protection features reduce external component count. Consider the thermal dissipation limits in the TO-252-5 package for high-load scenarios.
