CS5203A-2GDPR3

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

The CS5203A-2GDPR3 is a fixed-output linear regulator from the CS5203A series, manufactured by onsemi. It provides a stable 3.3 V output with a maximum current capacity of 3.0 A and an accuracy of ±2.0%. The device operates with an input voltage range up to 17 V and features a low dropout voltage of 1.15 V at full load. Designed for surface-mount applications, it utilizes a D2PAK-3 package (TO-263AA). Key electrical characteristics include a maximum quiescent current of 10 mA and a Safe Operating Area (SOA) protection circuit.

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

Verify the specific suffix GDPR3 against official datasheets to confirm the tape-and-reel packaging format and fixed 3.3 V output variant. Ensure compatibility with existing PCB footprints for the D2PAK-3 package. Cross-reference manufacturer lot codes and RoHS compliance documentation prior to integration into production assemblies.

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

Select this component when a fixed 3.3 V rail is required with up to 3 A continuous current capability. It serves as a direct pin-compatible replacement for LT1085 family regulators but offers superior dropout performance. Consider its thermal dissipation requirements in the D2PAK-3 package relative to the expected ambient temperature and load conditions.

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

This part belongs to the CS5203A series of adjustable and fixed linear regulators produced by onsemi. The series includes variants for different fixed outputs such as 1.5 V, 3.3 V, 5.0 V, and adjustable versions ranging from 1.25 V to 13 V. These regulators are designed to replace older bipolar LDO technologies with improved efficiency and lower dropout characteristics.

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

The CS5203A-2GDPR3 is pin-compatible with the LT1085 family of linear regulators. When substituting, verify that the thermal management solution accommodates the specific dropout voltage characteristics of the CS5203A series compared to legacy components.
