BA09CC0WT

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

The BA09CC0WT is a fixed-output low-dropout (LDO) linear regulator manufactured by ROHM Semiconductor, designed for applications requiring stable voltage regulation with high current capability. It features a PNP output transistor architecture that enables low saturation voltage characteristics. The device provides a fixed output voltage with an accuracy of ±2.0% at 25°C and supports a maximum output current of 1A. It operates within an input voltage range of 4V to 25V and includes comprehensive protection mechanisms such as thermal shutdown, over-current protection, and over-voltage protection. The typical dropout voltage is 0.3V at 0.5A output current, ensuring efficient performance under varying load conditions.

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

Verify the specific ordering suffix and package variant when sourcing, as ROHM offers multiple pin-compatible options like the BA09CC0WFP-E2 in different packages. Confirm RoHS compliance status and check for any end-of-life notices or last-time-buy recommendations from authorized distributors. Ensure the selected component matches the required thermal dissipation capabilities for your application design.

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

Select this component when a fixed 9V output with 1A current capacity is required in a TO-220FP-5 package. Consider the PNP topology for lower dropout voltage compared to NPN-based regulators. Evaluate thermal management requirements due to power dissipation at higher input-to-output voltage differences. Verify compatibility with external output capacitors, typically requiring values around 22µF for stability.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

The BA09CC0WT belongs to ROHM's BAxxCC0 series of fixed-output LDO regulators. This family is characterized by robust protection features and high reliability, suitable for demanding environments. The device is part of a broader lineup offering various fixed output voltages, all sharing similar protection architectures and packaging options to simplify design-in processes across different product lines.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

BA09CC0WFP-E2 is a documented substitute with identical electrical specifications but housed in a TO-252-5 surface-mount package instead of the through-hole TO-220FP-5. When replacing, ensure the PCB layout accommodates the different footprint and verify that thermal performance remains adequate for the new package type.
