MAX8511

19-2732; Rev 4; 8/11 MAX8510/MAX8511/MAX8512 + + Ultra-Low-Noise, High PSRR, Low-Dropout, 120mA Linear Regulators General Description The MAX8510/MAX8511/MAX8512 ultra-low-noise, lowdropout (LDO) linear regulators are designed to deliver up to 120mA continuous output current. These regulators achieve a low 120mV dropout for 120mA load current. The MAX8510 uses an advanced architecture to achieve ultra-low output voltage noise of 11µVRMS and PSRR of 54dB at 100kHz. The MAX8511 does not require a bypass capacitor, hence achieving the smallest PC board area. The MAX8512’s output voltage can be adjusted with an external divider. The MAX8510/MAX8511 are preset to a variety of voltages in the 1.5V to 4.5V range. Designed with a P-channel MOSFET series pass transistor, the MAX8510/MAX8511/ MAX8512 maintain very low ground current (40µA). The regulators are designed and optimized to work with low-value, low-cost ceramic capacitors. The MAX8510 requires only 1µF (typ) of output capacita...
