MAX1589ETT180+T

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

The MAX1589ETT180+T is a low-dropout linear regulator manufactured by Analog Devices Inc./Maxim Integrated. It operates from an input voltage range of +1.62V to +3.6V and delivers a guaranteed continuous load current of 500mA with a typical dropout voltage of 175mV at full load. The device features a preset output voltage of 1.8V with ±0.5% initial accuracy. It includes an active-low open-drain reset output that remains asserted for at least 70ms after regulation. The component utilizes a 6-pin TDFN package (3mm x 3mm) and supports an operating temperature range of -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

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

Verify the specific ordering suffix '180' confirms the 1.8V fixed output voltage variant. Confirm the '+T' designation indicates tape-and-reel packaging. Ensure the manufacturer is identified as Analog Devices Inc. or Maxim Integrated. Check for RoHS compliance status if required by project specifications. Validate the package type matches the 6-pin TDFN form factor.

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

Select this component for portable battery-powered equipment requiring stable voltage regulation under varying load conditions. The low dropout characteristic allows operation near the end-of-life battery voltage. Ensure input voltage does not exceed 3.6V. Verify thermal management requirements for the TDFN package if high power dissipation is expected. Consider the reset output timing for microprocessor initialization sequences.
