Overview

The LM337IMP is a voltage Regulators Linear, Low Drop Out (LDO) Regulator made by Texas Instruments in a SOT-223-4 package with 4 pins. 0.003%Vout 0℃~+125℃@(Tj) 1 1.25V~37V 1.5A 40V 77dB@(120Hz) Adjustable Negative Over Current Protection、Over Temperature Protection、Short Circuit Protection SOT-223-4 Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS.

PCBKit's library has its KiCad symbol (Regulators:REG3+1 1ADJ-2IN-3OUT+4IN, from CERN's library) and its footprint (ICs And Semiconductors SMD:SOT230P700X180-4N, from CERN's library), ready for a KiCad board. 646 are in stock at JLCPCB (part C527400). 1 open-source board in 1 repository on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the LM337IMP?

Yes. The symbol is Regulators:REG3+1 1ADJ-2IN-3OUT+4IN and the footprint ICs And Semiconductors SMD:SOT230P700X180-4N, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM337IMP?

SOT-223-4, with 4 pins. Its footprint is drawn on this page.

Where is the LM337IMP datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM337IMP?

JLCPCB lists it as part C527400, with 646 in stock; the sellers' links on this page open their listings.

What can replace the LM337IMP?

Parts like it in the library: the LM317EMP by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM337IMP?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
