TPS7A1633DGNR

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

TPS7A1633DGNR from Texas Instruments, in a HVSSOP-8-EP. 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 OUT power_out Regulator output pin; a capacitor of at least 2.2 µF must be tied from this pin to ground to assure stability, with TI recommending a 10-µF ceramic capacitor to maximize AC performance.
2 FB/DNC unconnected For the fixed-voltage TPS7A1633 (3.3 V) version this pin must be left unconnected and not routed to any electrical net, not even GND or IN (on the adjustable version this pin is the error-amplifier feedback input).
3 PG output Power-good open-collector output; leave open or connect to GND if the power-good function is not needed, and it can be pulled up to any rail of 5 V or lower.
4 GND power_in Ground pin for the device.
5 EN input Enable pin that turns the regulator on when VEN ≥ VEN_HI and off when VEN ≤ VEN_LO; if unused, tie to IN, ensuring VEN never exceeds VIN.
6 NC unconnected No-connect pin that can be left open or tied to any voltage between GND and IN.
7 DELAY output Delay pin; connect a capacitor to GND to set the power-good delay time (charged by the internal DELAY pin current), or leave open if the reset/delay function is not needed.
8 IN power_in Regulator input supply pin; a capacitor of at least 0.1 µF must be tied from this pin to ground for stability, with TI recommending a 10-µF ceramic capacitor close to the device to reduce sensitivity to PCB layout.
9 PowerPAD power_in Exposed thermal pad that should be soldered to the PCB ground plane to enhance thermal performance; it can be left floating but TI highly recommends connecting it to GND.

Key specifications

Package HVSSOP-8-EP
Category Power Management (PMIC)
Pins 9

CAD (KiCad official)

  • Symbol: TPS7A1633DGNR
  • Footprint: Package_SO:HVSSOP-8-1EP_3x3mm_P0.65mm_EP1.57x1.89mm
  • 3D model: HVSSOP-8-EP, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.0 mm nominal HVSSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: tps7a1633dgnr-etched.step / tps7a1633dgnr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps7a1633dgnr.step / tps7a1633dgnr.glb are the bare package body.
