LP3985IM5X-3.0

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

LP3985IM5X-3.0 from Texas Instruments, in a SOT-23-5. 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 IN power_in Input supply voltage, 2.5 V to 6 V, provides power to the low-dropout regulator.
2 GND power_in Common ground reference.
3 EN input Enable input logic control; logic high (≥1.4 V) enables regulator operation, logic low (<0.4 V) disables regulator with shutdown current ≤1.5 µA.
4 BYPASS bidirectional Optional external bypass capacitor connection (0.01 µF typical) to high-impedance bandgap reference node for output noise reduction without affecting load transient response.
5 OUT output Regulated output voltage, 3.0 V nominal, capable of supplying up to 150 mA continuous load current with 100 mV maximum dropout at full load.
