BA03CC0T

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

The BA03CC0T is a fixed-output low-dropout (LDO) linear regulator manufactured by ROHM Semiconductor. It provides a stable 3.3 V output with a maximum continuous current of 1 A. The device operates within an input voltage range of 4 V to 25 V and withstands up to 35 V. Key electrical parameters include a typical dropout voltage of 0.3 V at 500 mA, a quiescent circuit current of 2.5 mA, and an output voltage accuracy of ±2.0% at 25°C. It features a ripple rejection of 55 dB and load regulation of 50 mV across the full load range.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• PNP output transistor architecture enabling low saturation voltage for efficient power management.
• Integrated thermal shutdown circuitry protects the IC from damage during overheating conditions.
• Built-in over-current protection prevents internal damage caused by output short circuits or excessive loads.

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

• General-purpose power supply regulation in electronic equipment.
• Battery-powered devices requiring stable voltage conversion.
• Industrial control systems utilizing robust linear regulation.

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

Verify the specific package variant upon ordering, as datasheets indicate TO-220FP-3 packaging while some listings reference TO-220-3. Confirm RoHS compliance and lead-free status with the supplier. Ensure the application design accounts for the 2 W power dissipation limit and appropriate heat sinking for the through-hole mounting style to maintain operation within the -40°C to 125°C temperature range.

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

Select this component when a fixed 3.3 V rail is required with high current capability up to 1 A. The PNP-based design offers lower dropout characteristics compared to standard NPN regulators. Consider the thermal performance requirements carefully, as the TO-220FP-3 package requires adequate PCB copper area or heatsinking to manage power dissipation under heavy loads and high input-output differentials.

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

This part belongs to ROHM's BA series of 1A fixed-output LDO regulators. Other variants in the family provide different fixed output voltages, such as the BA09CC0T for 9 V outputs. These components share identical pinouts, protection features, and packaging, allowing for flexible design choices based on required voltage levels without changing the physical footprint.

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

Direct substitutes within the same series include BA05CC0T (5.0 V), BA09CC0T (9.0 V), and BAJ0CC0T (variable/other). Verify that replacement parts match the 3.3 V output requirement if voltage specificity is critical. All listed alternatives share the same TO-220FP-3 package and protection feature set.
