CS5258-1GT5

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

The CS5258-1GT5 is a positive adjustable linear regulator (LDO) manufactured by onsemi, designed for high-current applications. It delivers an output current of 8A with a maximum dropout voltage of 1.2V at full load. The device supports an input voltage range up to 13V and provides an adjustable output voltage between 1.25V and 5V. Key electrical specifications include a quiescent current of 10mA and a power supply rejection ratio (PSRR) of 80dB at 120Hz. It features comprehensive protection mechanisms including overcurrent, thermal shutdown, and short-circuit protection, operating within a junction temperature range of 0°C to 70°C in a TO-220-5 package.

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

Verify component authenticity through authorized onsemi distributors due to the availability of counterfeit parts in the market. Confirm that the specific suffix GT5 matches the required TO-220-5 leaded package configuration. Check for RoHS compliance status as older revisions may not meet current environmental directives. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent package damage before soldering.

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

Select this component when a fixed output voltage is not required and an adjustable range up to 5V is needed. Consider the thermal performance of the TO-220-5 package under continuous 8A load conditions. Evaluate the input-output voltage differential to ensure it remains within the specified dropout limits for optimal efficiency. Compare against the CS5257A-1GT5 if lower current requirements allow for potential cost or size optimization.

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

This part belongs to the CS525x series of high-current LDO regulators from onsemi, originally developed by Cherry Semiconductor. The series includes variants such as the CS5257A-1GT5 (7A) and CS52510-1GT5 (10A), offering scalable current capabilities. These regulators are characterized by their separate control and power input architecture, which enables superior dropout performance compared to conventional PNP-NPN designs.

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

The CS5257A-1GT5 serves as a lower-current alternative within the same family. Verify pin compatibility and thermal requirements when substituting with other 8A LDOs from different manufacturers.
