MC79L05ACDR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8

MC79L05ACDR from Texas Instruments, in a SOIC-8. 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 OUTPUT power_out Regulated negative output voltage of the 3-terminal fixed negative regulator, rated for up to 100 mA output current.
2 INPUT power_in Negative unregulated input voltage; internally connected to pins 3, 6 and 7 (input voltage range per device variant, e.g. -7 V to -20 V for the 79L05).
3 INPUT power_in Negative unregulated input voltage; internally connected to pins 2, 6 and 7 (input voltage range per device variant, e.g. -7 V to -20 V for the 79L05).
4 NC unconnected No internal connection.
5 COMMON power_in Common (ground) reference terminal of the 3-terminal negative voltage regulator.
6 INPUT power_in Negative unregulated input voltage; internally connected to pins 2, 3 and 7 (input voltage range per device variant, e.g. -7 V to -20 V for the 79L05).
7 INPUT power_in Negative unregulated input voltage; internally connected to pins 2, 3 and 6 (input voltage range per device variant, e.g. -7 V to -20 V for the 79L05).
8 NC unconnected No internal connection.
