LP2992IM5X-1.8

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

LP2992IM5X-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 power_in Input supply pin; use a capacitor of 1µF or larger from this pin to ground. The new-chip supply input range is 2.5 V to 16 V (absolute maximum continuous input 18 V).
2 GND power_in Ground reference pin for the regulator; all voltages are specified with respect to GND.
3 ON/OFF input Enable pin for the LDO: driving high enables the device and driving low disables it, with thresholds given in the Electrical Characteristics table; tie to VIN if unused and keep the enable voltage within 0 V to 16 V (new chip).
4 BYPASS input Bypass pin for low-noise operation; an external capacitor between BYPASS and ground reduces reference voltage noise, and the bypass voltage is 1.2 V.
5 OUT power_out Regulator output; use a capacitor of 2.2µF or larger from this pin to ground, keeping the effective output capacitance at the pin above 1µF, with output current up to 250 mA.
