MAX8559ETA11+

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

The MAX8559ETA11+T is a dual low-noise, low-dropout linear regulator manufactured by Analog Devices Inc./Maxim Integrated. It operates from an input voltage range of 2.5V to 6.5V and delivers up to 300mA continuous output current per channel. The device features independent shutdown controls and utilizes internal P-channel MOSFET pass transistors for high efficiency. Factory preset outputs are available between 1.5V and 3.3V. This specific variant provides fixed 1.85V outputs on both channels A and B.

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

Verify the exact suffix against the manufacturer's official documentation to confirm lead-free status and package type. Confirm availability as this component may be subject to discontinuation or limited stock. Ensure the ordering code matches the required output voltage configuration before procurement.

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

Select this part when dual isolated rails are required in space-constrained portable designs. The TDFN-EP-8 package offers superior thermal dissipation compared to UCSP options. Verify that the required output voltages match the factory presets or consult the manufacturer for custom voltage configurations.

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

This component belongs to the MAX8559 family of dual low-noise linear regulators designed primarily for battery-powered applications. The series is characterized by low quiescent current and small solution size. The MAX8559ETA11+T specifically denotes the TDFN package variant with fixed 1.85V outputs on both channels.

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

Direct replacements include other variants within the MAX8559 family such as MAX8559ETAJJ-T or MAX8559ETAAJ-T, which share identical pinouts and electrical characteristics but offer different factory preset output voltages.
