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.
