TPS71533DCKR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SC-70-5

TPS71533DCKR from Texas Instruments, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No connect pin; not connected internally; connect to ground for best thermal performance or leave floating.
2 GND power_in Ground pin.
3 NC unconnected No connect pin; not connected internally; connect to ground for best thermal performance or leave floating.
4 IN power_in Input supply pin; operates from 2.5V to 24V; requires 0.1µF or larger capacitor to ground.
5 OUT power_out Regulated output at 3.3V nominal; requires 1µF or larger capacitor to ground.
