Foshan Blue Rocket Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89
78L09T from Foshan Blue Rocket Elec, in a SOT-89. 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 | OUT | power_out | Regulated +9 V output. Typical output voltage 9.0 V (min 8.55 V, max 9.45 V) at Io = 40 mA. Requires a 0.1 uF output capacitor to ground for stability. |
| 2 | GND | power_in | Ground / common return for input and output. Also serves as the thermal/heat-sink tab on SOT-89. |
| 3 | IN | power_in | Unregulated DC input. Absolute maximum 30 V; recommended operating input 11.5 V to 23 V for the 9 V output. A 0.33 uF bypass capacitor to ground is recommended close to the pin. |
