CS8281YDP5

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

The CS8281YDP5 is a dual-output linear voltage regulator from onsemi, housed in a D2PAK-5 surface-mount package. It provides a fixed 100 mA output at 3.3 V and a separate 250 mA output at 5.0 V. Designed for low-power applications, this Micropower Low Dropout Regulator features an enable control pin to manage power consumption. The device operates within a standard temperature range and offers stable regulation for sensitive electronic circuits requiring multiple voltage rails.

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

• Dual independent output channels providing simultaneous 3.3 V and 5.0 V regulation
• Integrated enable functionality for precise power management and shutdown control
• Micropower design optimized for low quiescent current applications

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

• Portable battery-powered consumer electronics
• Embedded systems requiring multiple logic voltage levels
• Industrial control modules with mixed-signal requirements

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

Verify the specific suffix YDP5 to confirm the D2PAK-5 surface mount package and lead-free status. Confirm that the enable pin configuration matches your circuit design requirements. Check for obsolescence notices as older PMIC families may have limited availability or end-of-life status from the manufacturer.

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

Select this component when a single IC solution is needed for both 3.3 V and 5.0 V rails. Ensure the total load current does not exceed the individual channel limits of 100 mA and 250 mA respectively. Consider thermal dissipation capabilities in the D2PAK package if operating near maximum current loads or high input-output differentials.

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

This part belongs to onsemi's CS8xxx series of Micropower LDO regulators. These devices are designed to replace discrete transistor solutions in compact designs. The CS8281 variant specifically addresses applications needing two distinct regulated voltages from a single unregulated source, simplifying board layout and reducing component count compared to using two separate single-output regulators.

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

Direct replacements include other dual-output LDOs from onsemi such as the CS8481YDP5, which offers similar voltage outputs but may differ in current ratings or package specifics. Verify pin compatibility and thermal performance before substituting.
