MAX8877EUK42+

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

The MAX8877EUK42+T is a low-noise, low-dropout linear regulator from the MAX8877 series. It provides a fixed 4.2 V output with a maximum load current of 150 mA. The device operates within an input voltage range of 2.5 V to 6.5 V and features a typical dropout voltage of 1.1 mV, with a maximum of 120 mV at 50 mA. Quiescent current is 100 uA. It includes overcurrent protection, thermal shutdown, and reverse polarity protection. Operating temperature ranges from -40°C to +85°C in an SOT-23-5 package.

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

Verify the exact suffix (e.g., +T) against official Analog Devices documentation, as it determines packaging and RoHS compliance. Confirm availability status directly with authorized distributors, as this component may be discontinued or subject to limited supply constraints. Ensure the ordering part number matches the specific voltage and package requirements for your design.

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

Select this variant when a fixed 4.2 V output is required. Compare dropout characteristics and quiescent current against other LDOs if battery life is critical. Verify that the 150 mA output current meets the load requirements. Consider the SOT-23-5 package size constraints during PCB layout.
