BA09CC0WFP-E2

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

The BA09CC0WFP-E2 is a fixed-output low-dropout (LDO) regulator from ROHM Semiconductor, housed in a TO-252-5 surface-mount package. It delivers a maximum output current of 1A with a fixed voltage accuracy of ±2.0% at 25°C. The device supports an input voltage range from 4V to 25V and withstands up to 35V. Key electrical parameters include a typical dropout voltage of 0.3V at 0.5A output, a circuit current of 2.5mA, and a ripple rejection of 55dB. Load regulation is specified at 50mV for currents between 5mA and 1A. It operates within a temperature range of -40°C to +125°C.

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

Verify the specific suffix E2 when ordering to ensure compatibility with RoHS directives and lead-free manufacturing processes. Confirm that the TO-252-5 package footprint matches your PCB design constraints. Check official ROHM documentation for the most recent status updates, as availability may vary by region and distributor. Ensure proper thermal management is planned given the power dissipation characteristics of the package.

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

Select this component when a fixed 9V output is required with high current capacity and wide input voltage tolerance. The TO-252-5 package offers a balance between thermal performance and board space efficiency compared to smaller SOT packages. Consider the ±2.0% accuracy specification against application requirements. Evaluate the need for the shutdown feature if system power sequencing is critical. Compare thermal resistance values against expected ambient temperatures to ensure reliable operation without excessive heatsinking.
