LP38853SX-ADJ

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-7

LP38853SX-ADJ from Texas Instruments, in a TO-263-7. 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 SS output Soft-start capacitor connection used to control the rise time of VOUT at turnon.
2 EN input Device enable pin: High = On, Low = Off.
3 IN input The unregulated voltage input.
4 GND power_in Ground.
5 ADJ output The feedback connection to set the output voltage.
6 OUT output The regulated output voltage.
7 BIAS input The supply for the internal control and reference circuitry.
8 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
