CS8101YDWFR20

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

The CS8101YDWFR20 is a precision micropower linear voltage regulator from onsemi, providing a fixed positive output of 5.0 V with a maximum load current of 100 mA. It features very low quiescent current, typically 70 µA at a 100 mA load, and operates within an input voltage range supporting low dropout performance. The device includes internal protection mechanisms such as thermal shutdown and current limiting. Packaged in a 20-SOIC format, it offers high accuracy for the output voltage and is designed for applications requiring stable power supply with minimal power consumption.

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

Verify the specific suffix YDWFR20 against the manufacturer's latest datasheet to confirm pinout compatibility and package dimensions. Ensure that the required output current and voltage specifications align with your circuit design before procurement. Check for any recent lifecycle status updates or obsolescence notices directly from onsemi distributors to avoid supply chain disruptions during production.

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

Select this component when a fixed 5 V rail is needed with minimal standby current consumption. Compare quiescent current specifications against other LDOs if battery efficiency is critical. Verify that the 20-SOIC package fits your PCB layout constraints. Consider the dropout voltage characteristics relative to your minimum input voltage to ensure regulation stability under all operating conditions.

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

This part belongs to the CS8101 series of micropower voltage regulators from onsemi. The series is characterized by its ability to maintain regulation with very low current draw, making it distinct from standard LDOs that may consume more quiescent current. The CS8101 family is designed for applications where power conservation is as important as voltage stability.

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

Cross-reference with CS8101 variants having different package suffixes if pin compatibility differs. Verify functional equivalence with other 5V 100mA LDOs only if their quiescent current and protection features match the original design requirements.
