UA78M09CKVURG3

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-3

UA78M09CKVURG3 from Texas Instruments, in a TO-252-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 INPUT power_in Unregulated supply input. Recommended input voltage range for the UA78M09 is 11.5 V to 26 V (absolute maximum 35 V). A 0.33 uF ceramic capacitor should be placed close to this pin for input decoupling.
2 COMMON power_in Common / ground reference terminal. Electrically bonded to the tab of the TO-252 (KVU) package, so the mounting pad conducts both ground and heat. Return path for the load current.
3 OUTPUT power_out Regulated 9-V output (typ 9.0 V, min 8.6 V, max 9.4 V at 25 degC). Sources up to 500 mA continuous with internal short-circuit current limiting (~250 mA short-circuit) and safe-area compensation. A 0.1 uF ceramic capacitor is recommended close to this pin for stability.
