BA80BC0WT

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

The BA80BC0WT is a fixed-output low-dropout (LDO) regulator manufactured by ROHM Semiconductor, designed for applications requiring stable voltage regulation with high current capability. It delivers a maximum output current of 1A with an output voltage accuracy of ±2.0% at 25°C. The device operates within an input voltage range of 9V to 16V and withstands up to 18V. Key electrical characteristics include a typical dropout voltage of 0.3V at 0.2A output, a ripple rejection of 55dB, and a load regulation of 35mV across the full load range. It requires a 22µF output capacitor and functions within an operating temperature range of -40°C to 105°C.

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

Verify the specific suffix 'WT' corresponds to the TO-220FP-5 package and tube packaging format as documented in official ROHM datasheets. Confirm that the component status is acknowledged as 'Last Time Buy' or end-of-life if applicable to your supply chain planning. Ensure compatibility with existing PCB footprints for the five-terminal TO-220FP-5 configuration before finalizing procurement orders.

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

Select this component when a fixed 8V output with 1A capacity is required alongside robust internal protection mechanisms. The wide operating temperature range makes it suitable for harsh environments. Consider the TO-220FP-5 package for through-hole mounting requirements where higher thermal dissipation is necessary compared to smaller surface-mount alternatives.

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

The BA80BC0WT belongs to the BAxxBC0 series of low-saturation regulators from ROHM Semiconductor. This family offers fixed output voltages ranging from 1.5V to 10V with consistent 1A output current capabilities. The series is characterized by its inclusion of overcurrent and thermal shutdown protections, providing reliable performance in various linear regulation applications without requiring external protective components.

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

The BD80FC0WFP-E2 is identified as a potential replacement option for the BA80BC0WFP-E2 variant, offering similar 1A/8V specifications. Verify pinout compatibility and package differences between the TO-220FP-5 and alternative packages before substitution. Consult official ROHM documentation for detailed comparison of electrical parameters and thermal characteristics.
