LM2575S-ADJ P+

JSMSEMI · DC-DC Converters · TO-263-5

LM2575S-ADJ P+ from JSMSEMI, in a TO-263-5. 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 Unregulated input supply pin; rated for 4V to 40V operation with an absolute maximum of 45V.
2 OUTPUT output Switching output of the internal power transistor, connected to the inductor and catch diode; output to common is -1V maximum (steady state).
3 COMMON power_in Common (ground) pin; the package tab is also COMMON.
4 FEEDBACK input Feedback input to the error amplifier; for the ADJ version the feedback voltage is 1.230V typical, setting Vo = 1.23(1+R1/R2).
5 ON/OFF input Active-low shutdown pin (on at 0V, off at 5V), allowed from -0.3V to VIN; VIL is 1.0V max and VIH is 2.2V min.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
