MAX8902A/MAX8902B
Low-Noise 500mA LDO Regulators
in a 2mm x 2mm TDFN Package
General Description
The MAX8902A/MAX8902B low-noise linear regulators
deliver up to 500mA of output current with only
16μV RMS of output noise in a 100kHz bandwidth. These
regulators maintain their output voltage over a wide
input range, requiring only 100mV of input-to-output
headroom at full load.
These LDOs maintain a low 80μA typical supply cur-
rent, independent of the load current and dropout volt-
age. The regulator control circuitry includes a
programmable soft-start circuit and short circuit,
reverse current, and thermal-overload protection. Other
features include an enable input and a power-OK out-
put (MAX8902B only).
The MAX8902A output voltage can be set to 1.5V, 1.8V,
2.0V, 2.5V, 3.0V, 3.1V, 3.3V, 4.6V, or 4.7V using the
SELA and SELB inputs. The MAX8902B output voltage
Features
o 1.7V to 5.5V Input Voltage Range
o 0.6V to 5.3V Output Voltage Range
o 16μV RMS Output Noise, 10Hz to 100kHz
o 80μA Operating Supply Current
o 92dB PSRR at 5kHz
o Guaranteed 500mA Output Current
o ±1.5% Output Accuracy Over Load, Line, and
Temperature
o 100mV (max) Dropout at 500mA Load
o < 1μA Shutdown Supply Current
o 700mA Short-Circuit Protection
o Thermal-Overload Protection
o Output-to-Input Reverse Current Protection
can be set between 0.6V and 5.3V with an external
resistor voltage-divider.
