LP2985IM5-2.7

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

LP2985IM5-2.7 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; the datasheet recommends a capacitor of 1µF or larger from this pin to ground, and the supply input range is 2.5 V to 16 V for the new chip.
2 GND power_in Ground pin for the regulator, to be connected with the input and output capacitor returns as close together as practical.
3 ON/OFF input Enable input for the LDO: driving it high enables the device and driving it low disables it, with thresholds given in the Electrical Characteristics table; tie to VIN if unused.
4 BYPASS bidirectional Noise-bypass pin where an external capacitor to ground reduces reference voltage noise; the datasheet gives a BYPASS voltage of 1.2 V and an absolute maximum of 3 V for the new chip.
5 VOUT power_out Regulator output; use a capacitor of 2.2µF or larger from this pin to ground, with nominal capacitance above 2.2µF and effective capacitance above 1µF after derating.
