hpbock/esp12-environment-sensor
Environment sensor that is powered by a 18650 battery using a dht22 to sense temperature and humidity. Connectivity is provided wireless using an esp12 sleeping deeply most of the time.
Yes. The symbol is Pinmap_Generic:Regulator_Linear_1GND_2IN_3OUT and the footprint Package_TO_SOT_SMD:SOT-89-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
SOT-89-3, with 3 pins. Its footprint is drawn on this page.
UMW publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C347191, with 37,191 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the AMS1117-3.3S by UMW, the AMS1117-3.3 by GOODWORK, the CJA1117B-3.3 by Jiangsu Changjing Electronics Technology (CJ) and the AZ1117CR-3.3TRG1 by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
