SPX3819M5-L-2-5

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

SPX3819M5-L-2-5 from MaxLinear, 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 Supply input; operating input range is 2.5V to 16V (absolute maximum -20V to +20V).
2 GND power_in Ground.
3 EN input Enable input, CMOS compatible: logic high (≥2V) enables, logic low (≤0.4V) or open shuts down the regulator; range 0.0V to VIN.
4 BYP passive Fixed-version internal reference bypass pin; connect 10nF to ground to reduce output noise (may be left unconnected if noise is not a concern).
5 VOUT power_out Regulator output (fixed 2.5V for the -2-5 option, up to 500mA); requires an output capacitor for stability.
