MS79L05
MSKSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89
MS79L05 from MSKSEMI, in a SOT-89. 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 (common) pin of the regulator; the datasheet gives no separate electrical limit for this pin. |
| 2 | OUT | power_out | Regulated -5 V output, with a maximum output current IO of 0.1 A; a 0.1 μF output bypass capacitor is recommended close to the regulator. |
| 3 | IN | power_in | Unregulated negative input with an absolute maximum input voltage Vi of -30 V; a 0.33 μF input bypass capacitor is recommended close to the regulator. |
