General Description
The MAX8510/MAX8511/MAX8512 ultra-low-noise, low-
dropout (LDO) linear regulators are designed to deliver up
to 120mA continuous output current from a tiny 5-pin
SC70 plastic package. 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 11VRMS 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
(40A).
The regulators are designed and optimized to work with
low-value, low-cost ceramic capacitors. The MAX8510
requires only 1F (typ) of output capacitance for stability
with any load. When disabled, current consumption drops
to below 1A.
