MAX1792EUA50

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

The MAX1792EUA50+ is a low-dropout linear regulator from Analog Devices/Maxim Integrated, housed in an 8-pin Power-µMAX package. It delivers a guaranteed 500mA load current with a typical dropout voltage of 130mV at full load. The device operates from an input supply ranging from +2.5V to +5.5V and provides a fixed 5.0V output. Key electrical parameters include a ground-pin current of 80µA (typical) and a shutdown current of 0.1µA. It features thermal overload protection, short-circuit protection, and an active-low reset output with a 4ms timeout.

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

Verify the specific suffix '50' confirms the fixed 5.0V output configuration. Confirm the 'EUA' designation corresponds to the 8-pin Power-µMAX package with an exposed thermal pad. Ensure compliance with RoHS standards if required by the application environment. Cross-reference the datasheet revision date to confirm pin descriptions and absolute maximum ratings match the intended design constraints.
