BD80C0AFPS-CE2

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

The BD80C0AFPS-CE2 is a low-saturation LDO regulator with an 8.0V fixed output and 1A current capability. It operates within a supply voltage range of 9.0V to 26.5V. The device features high output voltage accuracy of ±1% at +25°C and ±3% across the full temperature range. Key electrical parameters include a typical circuit current of 0.6mA, dropout voltage of 0.3V at 500mA, and ripple rejection of 50dB at 120Hz. It is housed in a TO252S-3 package and supports temperatures from -40°C to +125°C.

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

Verify the specific suffix CE2 matches the required tape-and-reel packaging quantity of 2000 units. Confirm the TO252S-3 package dimensions align with PCB footprint requirements. Ensure design margins account for the absolute maximum ratings, particularly regarding junction temperature and surge voltages exceeding 35V.

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

Select this component when a fixed 8.0V rail is required with up to 1A load current. Verify input voltage stability remains above the 9.0V minimum startup threshold. Consider thermal resistance values based on the intended PCB copper area, as heat dissipation significantly impacts performance in the TO252S-3 package under high load conditions.

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

This part belongs to ROHM's automotive-grade LDO series designed for robust power management. It integrates error amplifiers and driver stages to maintain regulation. The silicon monolithic construction ensures reliability in harsh environments. It is distinct from adjustable variants and higher-voltage models within the broader product family.

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

BD80C0AFP2-C is a similar 1A LDO but offers a 35V withstand voltage and different pinout/package configuration. Verify compatibility before substitution as internal block diagrams and thermal characteristics may differ between the TO252S-3 and TO263-3F packages.

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

Can ceramic capacitors be used for the output?

Yes, ceramic capacitors are supported provided they meet the minimum capacitance of 1μF and ESR requirements within the specified operating temperature range.

What happens if the junction temperature exceeds the limit?

The Thermal Shutdown Protection (TSD) circuit detects excessive temperature and forces the output to turn off to prevent device damage.
