LP2985-33DBVR

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

LP2985-33DBVR from Texas Instruments, in a SOT-23-5. 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 VIN power_in Input supply voltage pin; accepts 2.5 V to 16 V supply with 1 µF minimum input filtering capacitor to ground.
2 GND power_in Ground reference; return path for input and output currents.
3 ON/OFF input Enable input pin; drive ≥0.85 V to enable output or ≤0.72 V to disable with internal pulldown.
4 BYPASS passive Reference bias node for internal bandgap; connect 10 nF capacitor to ground to achieve 30 µVRMS output noise and >70 dB PSRR at 1 kHz.
5 VOUT output Regulated 3.3 V output (±0.5% accuracy typical) from 0 to 150 mA load; requires 2.2 µF minimum output capacitor with ESR ≤1 Ω for stability.
