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.
The linear regulator has been optimized for noise
sensitive applications. The device includes an
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.
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.
The AMS3120 is available in a thermally enhanced
SOIC-8 EDP package, and it is rated for -40°C to
+125°C temperature range.
