SPX3819M5-L-1-2

MaxLinear · Linear Voltage Regulators (LDO) · SOT-23-5

SPX3819M5-L-1-2 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 Input supply pin; recommended input voltage is +2.5V to +16V, with an absolute maximum range of -20V to +20V.
2 GND power_in Ground reference pin for the regulator.
3 EN input Enable input: logic high (VIH ≥ 2.0V) enables the regulator and logic low (VIL ≤ 0.4V) disables it; it may be tied directly to VIN, and the recommended enable voltage range is 0.0V to VIN with an absolute maximum of -20V to +20V.
4 ADJ/BYP passive Adjust/bypass pin: on the adjustable version it is the feedback input for a resistor divider (VOUT = 1.235V × [1 + R1/R2], with R2 > 10 kΩ), and on fixed versions it is the internal reference bypass pin where an optional 10nF capacitor significantly reduces output noise.
5 VOUT power_out Regulated 500mA output; an output capacitor is required for stability (a 2.2µF aluminum electrolytic or 1µF tantalum works in most applications).
