TL751L12CDR

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

TL751L12CDR from Texas Instruments, in a SOIC-8. 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 OUTPUT power_out Regulated 12-V output (11.52 V to 12.48 V at 25°C) delivering 0 to 150 mA, requiring a 10-μF output capacitor with ESR below 0.4 Ω.
2 COMMON power_in Ground/common reference pin, connected internally with the other COMMON pins (3, 6, 7).
3 COMMON power_in Ground/common reference pin, connected internally with the other COMMON pins (2, 6, 7).
4 NC unconnected No internal connection.
5 ENABLE input Active-low TTL/CMOS-compatible enable input; high level (2 V to 15 V) disables the output into high impedance, low level is -0.3 V to 0.8 V at 25°C.
6 COMMON power_in Ground/common reference pin, connected internally with the other COMMON pins (2, 3, 7).
7 COMMON power_in Ground/common reference pin, connected internally with the other COMMON pins (2, 3, 6).
8 INPUT power_in Regulator input supply, 13 V to 26 V recommended for the 12-V version, with 60-V transient and -15 V continuous reverse rating tolerance as stated (26 V continuous max).
