MAX8902BATA+T

The MAX8902BATA+T is a low noise, high PSRR, low dropout (LDO) linear regulator in 8 pin TDFN package. It delivers up to 500mA of output current with only 16μVRMS of output noise in 100KHz bandwidth. This regulator maintains its output voltage over a wide input range which requires only 100mV of input to output dropout at full load. The MAX8902B maintains low 80μA typical supply current which is independent of load current and dropout voltage. The regulator control circuitry includes a programmable soft start circuit, short circuit, reverse current and thermal overload protection. The MAX8902B output voltage can be set between 0.6V and 5.3V with an external resistor voltage divider.

• Input voltage range from 1.7V to 5.5V
• Operating temperature range from -40°C to 125°C
• Power supply rejection ratio of 62dB at f=100KHz, 85dB at f=10KHz and 92dB at f=5KHz (IOUT=10mA)
• Load regulation of 0.02% and line regulation of 0.0%
• ±1.5% output accuracy over load, line and temperature
• 150mV dropout at 500mA load (VIN = 1.7V)
• Less than 1μA shutdown supply current
• 700mA short circuit protection
• Enable input and power-OK output
