CS5201-1GT3

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

The CS5201-1GT3 is a 1.0 A adjustable linear regulator from onsemi, housed in a TO-220-3 package. It provides an output voltage range of 1.25 V to 5.5 V with ±1.0% accuracy over temperature. The device features a typical dropout voltage of 1.0 V at full load and includes overcurrent and thermal shutdown protection. Designed for post-regulation and microprocessor supplies, it operates within a supply voltage limit of 7.0 V and supports an operating temperature range of -40°C to +70°C.

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

Verify the specific suffix GT3 corresponds to the TO-220-3 straight package configuration as listed in the ordering information. Confirm that the application design respects the maximum supply voltage of 7.0 V and the junction temperature limits to ensure reliable operation. Check for required heatsinking based on calculated power dissipation and ambient temperature conditions.

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

Select this component when a fixed 1.0 A linear regulator is insufficient and adjustable output between 1.25 V and 5.5 V is required. It is appropriate for designs needing pin compatibility with the LT1086 family. Ensure the input-output differential does not exceed 7.0 V to prevent damage during short-circuit or power-up conditions without additional clamp circuitry.

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

This part belongs to the CS5201 series of adjustable linear regulators manufactured by onsemi. The series is designed to provide high current output with precise voltage regulation. The CS5201-1 variant specifically targets the 1.0 A current rating, distinguishing it from other current capabilities within the broader product line while maintaining similar protection features and package options.

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

The datasheet states the CS5201 is pin compatible with the LT1086 family of linear regulators. Designers may consider LT1086 variants as functional substitutes if electrical parameters such as dropout voltage and current limits meet the specific application requirements.
