The MAX8840/MAX8841/MAX8842 ultra-low-noise, low-dropout
(LDO) linear regulators are designed to deliver
up to 150mA continuous output current. These regulators
achieve a low 120mV dropout for 120mA load current.
The MAX8840 uses an advanced architecture to
achieve ultra-low output voltage noise of 11µVRMS and
PSRR of 54dB at 100kHz.
The MAX8841 does not require a bypass capacitor,
hence achieving the smallest PC board area. The
MAX8842 output voltage can be adjusted with an external
divider.
The MAX8840/MAX8841 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 MAX8840/MAX8841/MAX8842 maintain very low ground current (40µA).
The regulators are designed and optimized to work with
low-value, low-cost ceramic capacitors. The MAX8840
requires only 1µF (typ) of output capacitance for stability
with any load. When disabled, current consumption drops
to below 1µA.
The MAX8840/MAX8841/MAX8842 are available in a tiny
1mm x 1.5mm x 0.8mm µDFN.
