BA30BC0T

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

The BA30BC0T is a fixed-output low-dropout (LDO) linear regulator manufactured by ROHM Semiconductor, designed for local power supply applications. It delivers a maximum output current of 1 A with an output voltage accuracy of ±2.0% at 25°C. The device features a PNP output transistor architecture, resulting in a typical dropout voltage of 0.3 V at an output current of 0.2 A. It operates within an input voltage range of 4 V to 16 V and withstands up to 18 V. Key protection mechanisms include built-in thermal shutdown and overcurrent protection circuits. The component is housed in a TO-220FP-3 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 specific suffix and revision code against the manufacturer's latest datasheet to ensure compatibility with required pin configurations and electrical tolerances. Confirm RoHS compliance status and packaging type (tube) matches project requirements. Check for end-of-life notifications as some variants in this series may be subject to discontinuation. Ensure proper heat sinking is planned given the TO-220FP-3 package and potential power dissipation.

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

Select the BA30BC0T when a fixed 3.0 V output is required with high current capability up to 1 A. Consider this component for designs needing low dropout voltage characteristics without the complexity of switching regulators. Evaluate thermal management needs based on the difference between input and output voltages at maximum load. Compare ripple rejection specifications if noise-sensitive analog sections are present in the system.

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

The BA30BC0T belongs to the BAxxBC0 series of secondary LDO regulators from ROHM Semiconductor. This family is characterized by its ability to provide stable 1 A output currents with high precision. The series is engineered for reliability in demanding environments, offering comprehensive protection features. It serves as a direct replacement for older discrete regulator solutions, simplifying board layout and reducing component count in power supply designs.

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

Direct pin-compatible substitutes within the same series include BA15BC0T, BA33BC0T, and BAJ0BC0T, depending on the required output voltage. Verify that alternative parts maintain the same TO-220FP-3 package and thermal characteristics. Cross-reference electrical parameters such as dropout voltage and quiescent current to ensure system performance remains unaffected.
