AMS3120  
2A Fast Transient Linear Regulator  
General Description  
Features  
The AMS3120 is a high performance linear regulator  
with very low dropout voltage and excellent transient  
response. It is designed to operate with wide input  
voltage range of 1.5 – 7Volts making it ideal for two  
step conversion while maintaining high efficiency for  
many power sensitive applications. The device is  
capable of supplying 2A of output current with a  
typical dropout voltage of 550mV at 2A. The product  
is available in either fixed or adjustable output  
voltage.  
VIN range: 1.5 – 7V  
Fixed and Adjustable output voltage as low  
as 0.6V  
2A maximum output current  
550mV typical dropout voltage at 2A  
Low self noise  
Optional Power Good (PG) output  
Enable (EN) pin for LDO on/off  
125µA typical supply current  
PSRR >40dB at 10KHz  
The linear regulator has been optimized for noise  
sensitive applications.  
The device includes an  
Stable with Electrolytic, Tantalum or  
Ceramic capacitors  
Enable pin for electrical on/off of the regulator.  
Forcing the Enable pin to logic low shuts down the  
LDO and reduces the supply current to less than  
1µA.  
Current Limit protection  
Over-Temperature Shutdown  
-40 to +125°C temperature range  
The product includes complete short-circuit and  
thermal protection. The combination of these two  
internal protection circuits gives the device a  
comprehensive safety system to safe guard against  
extreme adverse operating conditions.  
Thermally enhanced SOIC-8 exposed  
paddle package  
RoHS & WEEE compliant  
Applications  
The AMS3120 is available in a thermally enhanced  
SOIC-8 EDP package, and it is rated for -40°C to  
+125°C temperature range.
