+description: low drop out voltage regulator
+keywords: IC, regulator
+# the AMS1117 I had used the SOT89-3 package, but I could not find the corresponding datasheet
+# the closest I could find is Diodes AP1117 https://www.diodes.com/assets/Datasheets/AP1117_R21.pdf
+# this SOR89-3 package measurement are provided by JEDEC TO-243
+# I used the SOT89 package footprint provided by TI https://www.nxp.com/docs/en/package-information/SOT89.pdf
