CS5231-3GDP5

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

The CS5231-3GDP5 is a linear regulator manufactured by onsemi, providing a fixed 3.3V output voltage with a tolerance of ±2%. It supports a maximum load current of 500mA while maintaining a quiescent current of 3mA at full load. The device features fast transient response capabilities and includes built-in protection mechanisms such as current limiting and thermal shutdown with hysteresis. Additionally, it offers a reverse output current capability of 450µA, making it suitable for auxiliary supply control applications.

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

Verify the exact package type and marking code against official onsemi documentation before procurement. Confirm that the specific suffix DP5 corresponds to the desired tape and reel or tube packaging configuration. Ensure compatibility with your PCB footprint design rules. Check for any recent product change notices regarding pinout or electrical characteristics updates.

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

Select this component when a fixed 3.3V output is required with moderate current demands up to 500mA. Consider its thermal performance under expected load conditions due to the linear regulation topology. Evaluate the need for reverse current protection if the output may be driven higher than the input. Compare quiescent current requirements against other LDO options if battery life is critical.

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

This part belongs to onsemi's lineup of linear regulators designed for general-purpose voltage regulation. It is distinct from switching regulators due to its simpler architecture and lower noise profile. The CS5231 series typically targets applications requiring reliable, low-cost voltage sources with basic protection features integrated directly into the silicon die.

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

Direct replacements must match the 3.3V output, 500mA current rating, and similar pinout. Verify thermal resistance values if operating near limits. Check if alternative packages offer better heat dissipation for the same electrical performance.
