LP2985IM5X-1.8

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

LP2985IM5X-1.8 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 input Input supply voltage: operate from 2.2 V to 16 V, with a minimum of VOUT + 1 V recommended for good regulation, and an absolute maximum input of 16 V.
2 GND power_in Common ground pin tied to the device substrate; ground pin current is typically 825 µA at a 150-mA load and 75 µA at a 1-mA load.
3 ON/OFF input Logic-high enable input whose voltage must be between 0 V and VIN; pulling it low puts the device in sleep mode with less than 1 µA quiescent current.
4 BYPASS bidirectional Bypass capacitor connection for low-noise operation; the datasheet's typical application uses a 0.01 µF bypass capacitor, and a 10-nF bypass capacitor reduces output noise to 30 µV typical.
5 OUT output Regulated output voltage delivering up to 150 mA, with an absolute maximum output voltage range of -0.3 V to 9 V.
