High PSRR, Low-Dropout, 150mA Linear Regulators

The MAX8891 MAX8892 low-dropout (LDO) linear regu- lators 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 con- sumption drops to below 1µA. These Regulators are available in a tiny 5-pin SC70 package. By Maxim Integrated Products
