AAT3238  
300mA MicroPower™  
High Performance LDO Linear Regulator  
PowerLinear  
General Description  
Features  
The AAT3238 MicroPower low dropout (LDO) linear  
regulator is ideally suited for portable applications  
where very fast transient response, extended battery  
life, and small size are critical. The AAT3238 has  
been specifically designed for high-speed turn-on  
and turn-off performance, fast transient response,  
good power supply ripple rejection (PSRR), and is  
reasonably low noise, making it ideal for powering  
sensitive circuits with fast switching requirements.  
Low Dropout: 400mV at 300mA  
Guaranteed 300mA Output  
High Accuracy: ±1.5%  
70µA Quiescent Current  
Fast Line and Load Transient Response  
High-Speed Device Turn-On and Shutdown  
High Power Supply Ripple Rejection  
Low Self Noise  
Short-Circuit Protection  
Over-Temperature Protection  
Uses Low Equivalent Series Resistance  
(ESR) Ceramic Capacitors  
Noise Reduction Bypass Capacitor  
Shutdown Mode for Longer Battery Life  
Low Temperature Coefficient  
Other features include low quiescent current, typical-  
ly 70µA, and low dropout voltage, typically less than  
400mV at the maximum output current level of  
300mA. The device is output short-circuit protected  
and has a thermal shutdown circuit for additional pro-  
tection under extreme operating conditions.  
Factory-Programmed Output Voltages  
SOT23 6-Pin or SC70JW 8-Pin Package  
The AAT3238 also features a low-power shutdown  
mode for extended battery life. A reference bypass  
pin has been provided to improve PSRR perform-  
ance and output noise by connecting a small exter-  
nal capacitor from the AAT3238's reference output to  
ground.  
Applications  
The AAT3238 is available in a Pb-free, space-saving  
6-pin SOT23 or 8-pin SC70JW package in factory-  
programmed voltages.
