MAX8891 - (MAX8891 / MAX8892) 150mA Linear Regulators

General Description

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.

19-4537; Rev 0; 3/09 www.DataSheet4U.com High PSRR, Low-Dropout, 150mA Linear Regulators General Description 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.
