Low-Noise, Low-Dropout, 200mA  
Linear Regulator  
General Description  
Features  
The MAX1598 low-noise, low-dropout linear regulator  
operates from a 2.5V to 6.5V input and delivers up to  
200mA Output Current  
Low Output Noise: 30µV  
RMS  
200mA. Typical output noise is 30µV  
, and typical  
RMS  
dropout is only 236mV at 200mA. The output voltage is  
preset to voltages from 2.5V to 5V in 100mV increments.  
Low 55mV Dropout at 50mA Output  
Low 85µA No-Load Supply Current  
Designed with an internal P-channel MOSFET pass  
transistor, the MAX1598 maintains a low 100µA supply  
current independent of the load current and dropout  
voltage. Other features include a 10nA logic-controlled  
shutdown mode, short-circuit and thermal-shutdown  
protection, and reverse battery protection. The device  
also includes an autodischarge function, which actively  
discharges the output voltage to ground when the  
device is placed in shutdown. The MAX1598 comes in  
a thin 5-pin SOT23 package.
