LM337IMPX-TP

TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-3

LM337IMPX-TP from TECH PUBLIC, in a SOT-223-3. 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 ADJ input Adjust pin; sets the output voltage (adjustable between -1.2V and -37V), with a reference voltage of -1.25V typical to the output.
2 VIN power_in Input of supply voltage; input-output voltage differential is limited to 40V maximum, and the tab is also marked VIN.
3 VOUT power_out Output of the regulator, adjustable between -1.2V and -37V with output current up to 1.5A.
