AAT3237  
300mA MicroPower™ LDO with PowerOK  
PowerLinear  
General Description  
Features  
The AAT3237 MicroPower low dropout (LDO) lin-  
ear regulator is ideally suited for portable applica-  
tions where low noise, extended battery life, and  
small size are critical. The AAT3237 has been  
specifically designed for low output noise perform-  
ance, fast transient response, and high power sup-  
ply rejection ratio (PSRR).  
Low Dropout: 400mV at 300mA  
Guaranteed 300mA Output  
High Accuracy ±1.5%  
70µA Quiescent Current  
High Power Supply Ripple Rejection  
Power-OK (POK) Output  
Fast Line and Load Transient Response  
Short-Circuit Protection  
Over-Temperature Protection  
Uses Low Equivalent Series Resistance  
(ESR) Ceramic Capacitors  
Shutdown Mode for Longer Battery Life  
Low Temperature Coefficient  
13 Factory-Programmed Output Voltages  
SOT23 6-Pin or SC70JW 8-Pin Package  
Other features include low quiescent current, typi-  
cally 70µA, and low dropout voltage, typically less  
than 400mV at full output current. The device is  
output short-circuit protected and has a thermal  
shutdown circuit for additional protection under  
extreme conditions.  
The AAT3237 also features a low-power shutdown  
mode for extended battery life. A Power-OK open-  
drain output signals when VOUT is in regulation.  
The AAT3237 is available in a Pb-free, space-sav-  
ing 6-pin SOT23 or 8-pin SC70JW package in 13  
factory-programmed voltages: 1.2V, 1.5V, 1.8V,  
2.0V, 2.3V, 2.5V, 2.7V, 2.8V, 2.85V, 2.9V, 3.0V,  
3.3V, or 3.5V.
