LP2985A-25DBVR

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

LP2985A-25DBVR 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 VIN power_in Input supply pin with 2.5 V to 16 V operating range; use ≥1 µF capacitor to GND.
2 GND power_in Ground reference.
3 ON/OFF input Enable pin; driving high (≥0.85 V) enables output, driving low (≤0.72 V) disables output and actively discharges VOUT.
4 BYPASS passive Bypass pin for bandgap reference; connect 10 nF capacitor to GND for low-noise operation with DC leakage ≤100 nA.
5 VOUT power_out Regulated 2.5 V output; use ≥2.2 µF capacitor to GND for stability.
