MAX882CSA

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

The MAX882CSA is a low-dropout linear regulator manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-pin SOIC package. It provides a fixed 3.3V output with a maximum current capability of 200mA. The device operates within an input voltage range of 2.7V to 11.5V and supports Dual Mode operation for adjustable outputs from 1.25V to 11V using external resistors. It features a typical quiescent current of 11µA and includes a standby mode drawing 7µA. The unit incorporates foldback current limiting, reverse-current protection, and thermal-overload protection.

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

Verify the specific suffix 'CSA' confirms the commercial temperature range (0°C to +70°C) and SOIC-8 packaging. Confirm RoHS compliance status as indicated in official documentation. Ensure the source document matches the manufacturer's current datasheet revision to validate all electrical parameters and pin configurations before integration.

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

Select this component when designing for battery-operated applications requiring ultra-low supply currents. The internal p-channel pass transistor ensures minimal quiescent current draw across the entire load range. Verify that the required output voltage aligns with the fixed 3.3V preset or falls within the 1.25V to 11V adjustable range defined by the Dual Mode architecture.

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

This part belongs to the MAX882/MAX883/MAX884 family of micropower regulators. While the MAX883 offers a 5V preset and the MAX884 also provides 3.3V, the MAX882CSA specifically designates the 3.3V variant in the commercial grade SOIC package. All family members share identical pinouts and core protection features.

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

Direct substitutes include the MAX884CSA, which shares the same 3.3V fixed output and pin configuration. For adjustable output requirements, any member of the MAX882/MAX883/MAX884 series can be utilized by configuring the SET pin with external resistors.
