CS8101YDR8

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

The CS8101YDR8G is a fixed-output linear regulator from onsemi, delivering a stable 5V output with a maximum current capacity of 100mA. It operates within an input voltage range up to 30V and maintains a typical dropout voltage of 0.6V at full load. The device features low quiescent current of 140µA and high power supply rejection ratio of 75dB at 120Hz. Integrated protections include over-temperature, over-voltage, reverse polarity, and short-circuit safeguards. It is housed in an 8-SOIC package and supports operation across a temperature range of -40°C to 125°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated comprehensive protection mechanisms including thermal shutdown, over-voltage lockout, reverse polarity blocking, and short-circuit limiting for robust system reliability.
• High power supply rejection ratio ensures clean output regulation against input line noise and ripple in sensitive analog or digital circuits.
• Fixed 5V output configuration simplifies design integration by eliminating external feedback resistor networks typically required for adjustable regulators.

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

Verify the exact suffix (e.g., G) as datasheets reference CS8101YDR8G. Confirm RoHS compliance status via manufacturer documentation. Check component lifecycle status as some listings indicate obsolescence. Ensure packaging type matches project requirements. Validate pinout compatibility during board redesign.

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

Select this component when a simple, cost-effective 5V source is needed for low-current loads. Consider the 100mA limit for peak demand scenarios. Evaluate thermal dissipation needs based on input-output differential voltage. Compare PSRR requirements against alternative LDOs if noise sensitivity is critical. Verify package availability for automated assembly processes.
