STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
L79L05ACUTR from STMicroelectronics, in a SOT-89-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference pin of the negative regulator, used as the common return for the input and output capacitors in the test circuit. |
| 2 | VIN | power_in | Negative input voltage pin, with an absolute maximum of -30 V for -5 to -9 V output versions and -35 V for -12 to -15 V versions, decoupled with CIN = 0.33 µF in the test circuit. |
| 3 | VOUT | power_out | Regulated negative output of -5 V (-4.8 to -5.2 V at 25 °C) for the L79L05AC, delivering up to 100 mA and decoupled with COUT = 0.1 µF in the test circuit. |
