LT1054IP

Texas Instruments · DC-DC Converters · PDIP-8

LT1054IP from Texas Instruments, in a PDIP-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 FB/SD input Shutdown input for low Iq operation, or error amplifier input for regulation.
2 CAP+ input Positive side of the external CIN capacitor.
3 GND power_in Ground reference pin.
4 CAP- input Negative side of the external CIN capacitor.
5 VOUT output Regulated output voltage.
6 VREF power_in Internal reference voltage output.
7 OSC input Oscillator control pin, used to adjust the switching frequency or to synchronize the device externally.
8 VCC power_in Supply pin.

CAD (KiCad official)

  • Symbol: LT1054IP
  • Footprint: Package_DIP:DIP-8_W7.62mm
  • 3D model: PDIP-8 (KiCad packages3D, STEP)
  • 3D model files: lt1054ip-etched.step / lt1054ip-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lt1054ip.step / lt1054ip.glb are the bare package body.
