Description

General part information

MAX8891 Series

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.ApplicationsBase StationsBluetooth Portable Radios and AccessoriesCellular and Cordless PhonesDigital CamerasPDA and Palmtop ComputersPersonal StereosPortable and Battery-Powered EquipmentWireless LANs
