CS5207-3GDPR3

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

The onsemi CS5207-3GDPR3 is a positive fixed linear regulator (LDO) in the PMIC category. It provides a fixed output voltage of 3.3V with a maximum continuous output current of 3A. The device features a maximum input voltage rating of 7V and exhibits a typical dropout voltage of 1.4V at full load. Key electrical specifications include a quiescent current of 10 mA and a power supply rejection ratio (PSRR) of 80 dB at 120 Hz. It incorporates overcurrent and overtemperature protection mechanisms for system reliability.

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

Verify component authenticity through authorized distribution channels due to potential availability of refurbished or counterfeit units. Confirm RoHS compliance status as historical data indicates non-compliance for this specific part number. Ensure the D2PAK-3 package matches the target PCB footprint design requirements before finalizing procurement decisions.

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

Select this component when a 3.3V output at up to 3A is required from an input source not exceeding 7V. Consider the 1.4V dropout voltage to ensure sufficient headroom between input and output under all operating loads. Evaluate the thermal performance in the D2PAK-3 package to maintain junction temperatures within the 0°C to 70°C operational range during continuous use.
