LT1054CP

Texas Instruments · DC-DC Converters · PDIP-8

LT1054CP from Texas Instruments, in a PDIP-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 FB/SD input Feedback/shutdown pin for regulation via error amplifier or low-Iq shutdown when pulled below 0.45V threshold.
2 CAP+ passive Positive terminal connection for external input capacitor CIN.
3 GND power_in Ground reference and device substrate connection.
4 CAP- passive Negative terminal connection for external input capacitor CIN.
5 VOUT output Regulated negative output voltage with 1.1V typical loss at 100mA for 3.5V ≤ VCC ≤ 15V.
6 VREF power_in Internal 2.5V reference voltage output (2.25V-2.75V range) for regulator feedback with 60µA output current limit.
7 OSC input Oscillator control pin for switching frequency adjustment (nominal 25kHz, 15-35kHz range) or external synchronization.
8 VCC power_in Positive supply voltage input from 3.5V to 15V (maximum 20V for regulated circuits with VOUT ≤ 15V).
