低壓差穩壓器 LDO BI 1.0A 1.3V 12V 5.0V 3.3V FIX

Description
AP1117 is a low dropout positive adjustable or fixed-mode 
regulator with 1A output current capability. The product is 
voltage specifically designed to provide well-regulated supply 
for low IC applications such as high-speed bus termination 
and low current 3.3V logic supply. AP1117 is also well suited 
for other applications such as VGA cards. AP1117 is 
guaranteed to have lower than 1.4V dropout at full load 
current making it ideal to provide well-regulated outputs of 
1.25 to 5.0 with 6.4V to 18V input supply. AP1117 is available 
in commercial temperature grade.
