MAX8510/MAX8511/  
MAX8512  
Ultra-Low-Noise, High PSRR,  
Low-Dropout, 120mA Linear Regulators  
General Description  
Features  
The MAX8510/MAX8511/MAX8512 ultra-low-noise, low-  
dropout (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  
Space-Saving SC70 and TDFN (2mm x 2mm) Packages  
● 11μV Output Noise at 100Hz to 100kHz

and PSRR of  
RMS  
● Stable with 1μF Ceramic Capacitor for Any Load  
Guaranteed 120mA Output  
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.  
Only Need Input and Output Capacitors (MAX8511)  
Output Voltages: 1.5V, 1.8V, 2.5V, 2.6V, 2.7V, 2.8V,  
2.85V, 3V, 3.3V, 4.5V (MAX8510/MAX8511) and  
Adjustable (MAX8512)  
The MAX8510/MAX8511 are preset to a variety of voltag-  
es 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).  
● Low 40μA Ground Current  
Excellent Load/Line Transient  
Overcurrent and Thermal Protection  
The regulators are designed and optimized to work with  
low-value, low-cost ceramic capacitors. The MAX8510  
requires only 1μF (typ) of output capacitance for stability  
with any load. When disabled, current consumption drops  
to below 1μA.
