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. 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. ♦ Space-Saving SC70 Package ♦ 65dB PSRR at 10kHz ♦ 120mV Dropout at 120mA Load ♦ Stable with 1µF Ceramic Capacitor for Any Load ♦ Guaranteed 150mA Output ♦ Only Need Input and Output Capacitors (MAX8891) ♦ Output Voltages: 1.5V, 1.8V, 2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 3V, 3.3V, 4.5V (MAX8891) and Adjustable (MAX8892) ♦ Low 40µA Ground Current ♦ Excellent Load/Line Transient ♦ Overcurrent and Thermal Protection
