LP2985AIM5-2.9

Texas Instruments · Linear Voltage Regulators (LDO) · SOT-23-5

LP2985AIM5-2.9 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 voltage; the datasheet gives an operating supply range of 2.5 V to 16 V and a recommended minimum VIN of 3.1 V or VOUT(MAX) plus the maximum dropout, whichever is greater.
2 GND power_in Common ground (device substrate).
3 ON/OFF input Logic high enable input; the ON/OFF input voltage is specified from 0 V to VIN.
4 BYPASS bidirectional Bypass capacitor connection for low-noise operation; the typical application uses a 0.01 µF CBYPASS.
5 OUT output Regulated output voltage; the output is specified for up to 150 mA of output current.
