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
RMS
Bandwidth (MAX8510)
● 78dB PSRR at 1kHz (MAX8510)
● 120mV Dropout at 120mA Load
ultra-low output voltage noise of 11μV
54dB at 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.
