Built-in over-current, over-temperature, and short-circuit protection means the LDO survives a downstream fault without latching off or damaging the pass element. The enable and reset control features allow sequencing — the reset output holds the load in reset until the 1.2 V rail is stable. ## 6-TDFN exposed-pad — thermal and layout notes The 500 mA output at 1.2 V from a 3.6 V input dissipates about 1.2 W — the exposed pad keeps the junction below the 125°C limit when the board copper area is adequate.","metaTitle":"MAX1589ETT120+ LDO Regulator, 1.2V Fixed, 500mA, 6-TDFN","metaDescription":"Analog Devices MAX1589ETT120+ LDO regulator, 1.2V fixed output, 500mA, 70dB PSRR, -40°C to 85°C, 6-WDFN exposed pad.
