TPS7A4901DGNT

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · MSOP-8-EP

TPS7A4901DGNT from Texas Instruments, in a MSOP-8-EP. 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 OUT output Regulator output; a capacitor ≥ 2.2 µF must be tied from this pin to ground to ensure stability.
2 FB input Input to the error amplifier; FB is used to set the output voltage of the device.
3 NC unconnected Not internally connected; this pin can either be left open or tied to GND.
4 GND power_in Ground pin, must be tied directly to the PowerPAD under the device.
5 EN input Enable input that turns the regulator on when VEN ≥ VEN(high) and off when VEN ≤ VEN(low); can be connected to IN if not used, VEN ≤ VIN.
6 NR/SS passive Noise-reduction/soft-start pin; an external capacitor here bypasses band-gap noise to reduce RMS output noise and sets the soft-start ramp time.
7 DNC unconnected Do not connect; do not route this pin to any electrical net, not even GND or IN.
8 IN power_in Input supply pin, input voltage range 3 V to 35 V (recommended operating conditions).
9 PowerPAD power_in Exposed thermal pad; must be either left open or tied to ground, and should be soldered to the PCB ground plane to enhance thermal performance.
