CS5205-1GDP3

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

The CS5205-1GDP3 is a fixed-output positive low-dropout (LDO) voltage regulator manufactured by onsemi. It provides a stable 1.8V output with a maximum load current of 1A. The device operates within an input voltage range of 2.5V to 6V and maintains a typical dropout voltage of 400mV at full load. It features a low quiescent current of 100µA and offers high power supply rejection ratio (PSRR). The component is housed in a compact D2PAK-3 surface-mount package, suitable for space-constrained portable applications.

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

Verify the exact part number suffix against official datasheets to confirm the fixed 1.8V output variant. Ensure the D2PAK-3 package outline matches your PCB footprint design. Cross-reference thermal resistance values for adequate heat dissipation planning in your specific enclosure environment.

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

Choose this regulator when a fixed 1.8V rail is required without external feedback networks. It is suitable for applications where input voltages remain above 2.5V. Consider its 1A current capability and thermal performance in the D2PAK-3 package relative to your system's power budget and ambient temperature conditions.

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

This component belongs to onsemi's LDO regulator family designed for portable electronics. It complements adjustable LDOs by providing a pre-set voltage option. The D2PAK-3 package is common for medium-power linear regulators requiring efficient thermal management in compact form factors.

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

Check for pin-compatible alternatives with identical 1.8V output and D2PAK-3 packaging. Verify that substitute parts meet the same 1A load current and 2.5V minimum input voltage specifications to ensure functional equivalence.
