MAX8891, MAX8892 高PSRR、低壓差、150mA線性穩(wěn)壓器

MAX8891, MAX8892 概述

The MAX8891/MAX8892 low-dropout (LDO) linear regulators are designed to deliver up to 150mA continuous output current. These regulators achieve a low 120mV dropout for 120mA load current.

The MAX8891 only requires an input/output capacitor, hence achieving the smallest PCB area. The MAX8892's output voltage can be adjusted with an external divider.

The MAX8891 is preset to a variety of voltages in the 1.5V to 4.5V range. Designed with a p-channel MOSFET series pass transistor, the MAX8891/MAX8892 maintain very low ground current (40μA).

The regulators are designed and optimized to work with low-value, low-cost ceramic capacitors. The MAX8891/MAX8892 require only 1μF (typ) of output capacitance for stability with any load. When disabled, current consumption drops to below 1μA.

These regulators are available in a tiny 5-pin SC70 package.
