MAX1589EZT130+T

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

The MAX1589EZT130+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 1.3V with ±0.5% initial accuracy. It includes an active-low open-drain reset output that remains asserted for at least 70ms after regulation is achieved. The component is housed in a 6-pin thin SOT-23 package and supports an operating temperature range from -40°C to +85°C.

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

• Utilizes an internal PMOS pass transistor to maintain low supply current independent of load and dropout voltage conditions.
• Integrates logic-controlled shutdown functionality that reduces supply current below 1µA when activated.
• Includes comprehensive protection mechanisms such as thermal-overload protection and short-circuit protection.
• Features a microprocessor supervisory circuitry that asserts a logic-low reset signal during power-up, power-down, and brownout conditions.
