CS5201-3GT3

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

The CS5201-3GT3 is a fixed positive linear low-dropout (LDO) voltage regulator manufactured by onsemi. It provides a stable 3.3 V output with a maximum load current of 1.0 A. The device features a typical dropout voltage of 1.2 V at full load and utilizes bipolar technology. It is housed in a TO-220AB package, designated by the suffix GT3, which indicates a specific lead form and packaging configuration for through-hole mounting.

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

Verify component authenticity as this part is obsolete and no longer manufactured by onsemi. Sourcing will likely involve third-party distributors or surplus stock. Confirm the exact package variant matches the TO-220AB specification and check for any manufacturing date codes that may affect long-term reliability in new designs.

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

Select this component only if legacy compatibility is required due to existing board layouts. For new designs, consider modern equivalents from the same manufacturer or competitors that offer improved efficiency or availability. Ensure the thermal management solution supports the TO-220AB package dissipation requirements under expected load conditions.

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

This device belongs to the CS5201 series of linear regulators. The base model CS5201 offers adjustable output options, while the CS5201-3 variant fixes the output at 3.3 V. The GT3 suffix specifies the physical package and termination style. This series is designed for applications requiring simple, low-noise voltage regulation with moderate current capabilities.

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

Publicly confirmed substitute part numbers are not available in the provided documentation. As the part is obsolete, engineers must identify cross-reference components based on pinout compatibility, electrical specifications, and package dimensions from other manufacturers.
