Low-Noise 500mA LDO Regulators

in a 2mm x 2mm TDFN Package

/MAX8902B

General Description

Features

The MAX8902A/MAX8902B low-noise linear regulators

deliver up to 500mA of output current with only

♦ 1.7V to 5.5V Input Voltage Range

♦ 0.6V to 5.3V Output Voltage Range

16µV

of output noise in a 100kHz bandwidth. These

RMS

♦ 16µV

Output Noise, 10Hz to 100kHz

RMS

regulators maintain their output voltage over a wide

input range, requiring only 100mV of input-to-output

headroom at full load.

♦ 80µA Operating Supply Current

♦ 92dB PSRR at 5kHz

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 a shutdown input and a power-OK out-

put (MAX8902B only).

♦ Guaranteed 500mA Output Current

♦

1.5ꢀ Output Aꢁꢁuraꢁy Oꢂer ꢃoad, ꢃine, and

Temperature

♦ 100mV (max) Dropout at 500mA ꢃoad

♦ < 1µA Shutdown Supply Current

♦ 700mA Short-Cirꢁuit Proteꢁtion

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

can be set between 0.6V and 5.3V with an external

resistor voltage divider.

♦ Thermal-Oꢂerload Proteꢁtion

♦ Output-to-Input Reꢂerse Current Proteꢁtion

♦ 2mm x 2mm x 0.8mm TDFN Paꢁkage
