MAX8505 Datasheet Step-down Regulator

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX8505 6m 19-2992; Rev 1; 9/10 EVAALVUAAILTAIOBNLEKIT 16-QSOP 3A, 1MHz, 1% Accurate, Internal Switch Step-Down Regulator with Power-OK m m x 4.

General Description

The MAX8505 step-down regulator operates from a 2.6V to 5.5V input and generates an adjustable output voltage from 0.8V to 0.85  VIN at up to 3A.

With a 2.6V to 5.5V bias supply, the input voltage can be as low as 2.25V.

The MAX8505 integrates power MOSFETs and operates at 1MHz/500kHz switching frequency to provide a compact design.

Key Features

  • 1% accurate output over load, line, and temperature variations. Adjustable soft-start is achieved with an external capacitor. During the soft-start period, the voltage-regulation loop is active. This limits the voltage dip when the active devices, such as microprocessors or ASICs connected to the MAX8505’s output, apply a sudden load current step upon passing their undervoltage thresholds. The MAX8505 features current-limit, short-circuit, and thermal-overload protection and enables a rugged de.
