Ultra-Low-Noise, High PSRR,
Low-Dropout, 120mA Linear Regulators
General Description
The MAX8510/MAX8511/MAX8512 ultra-low-noise, low-
dropout (LDO) linear regulators are designed to deliver
up to 120mA continuous output current. These regula-
tors achieve a low 120mV dropout for 120mA load cur-
rent. The MAX8510 uses an advanced architecture to
achieve ultra-low output voltage noise of 11µV_RMS 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 volt-
ages 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 capacitance for stability
with any load. When disabled, current consumption drops
to below 1µA.
Package options include a 5-pin SC70 and a tiny 2mm x
2mm x 0.8mm TDFN package.
