BA03CC0WT

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

The BA03CC0WT is a fixed-output low-dropout (LDO) linear regulator manufactured by ROHM Semiconductor, designed for stable voltage regulation in power management applications. It delivers a fixed output voltage of 3.3 V with a maximum output current capability of 1 A. The device operates within an input voltage range of 4 V to 25 V and supports a withstand voltage of up to 35 V. Key electrical specifications include a typical dropout voltage of 0.3 V at 0.5 A load, a circuit current of 2.5 mA, and an output accuracy of ±2.0% at 25°C. It features ripple rejection of 55 dB and load regulation of 50 mV from 5 mA to 1 A. The component is housed in a TO-220FP-5 package, suitable for through-hole mounting, and operates across a temperature range of -40°C to 125°C.

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

Verify the specific suffix 'WT' corresponds to the TO-220FP-5 full pack configuration when sourcing. Confirm RoHS compliance status and lead time requirements directly with authorized distributors or the manufacturer. Ensure that the procurement order matches the exact part number to avoid compatibility issues with existing board designs.

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

Select this component when a fixed 3.3 V output is required with high current capacity up to 1 A. The integrated shutdown feature makes it suitable for systems requiring power sequencing or standby modes. Consider the TO-220FP-5 package for applications where thermal dissipation is critical and through-hole mounting is preferred over surface-mount alternatives.

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

This LDO regulator belongs to ROHM's standard series offering various output currents and packaging options. It is part of a broader family of low-saturation regulators designed for diverse power management needs. The BA03CC0WT specifically addresses applications requiring robust protection features and precise voltage regulation in a durable through-hole package.

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

Compatible substitutes within the same ROHM series include variants with different output voltages or shutdown configurations, such as the BA033CC0T for similar performance in a TO-220-3 package. Cross-model selection should verify pin compatibility and thermal characteristics.
