LP3985IM5-2.7

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

LP3985IM5-2.7 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 IN power_in Input voltage for the low-dropout regulator, 2.5 V to 6 V supply range
2 GND power_in Common ground return
3 EN input Enable input logic (enable high); voltage ≥1.4 V enables device start-up, voltage ≤0.4 V disables to ≤1.5 μA shutdown current
4 BYPASS output Bypass capacitor connection (0.01 μF recommended) to high impedance bandgap reference node, charged by internal 70-μA current source for noise reduction from 30 μVRMS typical
5 OUT power_out Regulated output voltage 2.7 V nominal, capable of delivering 150 mA maximum load current with 100 mV maximum dropout at rated current
