TPS76801QPWPRQ1

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · HTSSOP-20-EP

TPS76801QPWPRQ1 from Texas Instruments, in a HTSSOP-20-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 GND/HSINK power_in Ground and heatsink pin.
2 GND/HSINK power_in Ground and heatsink pin.
3 GND power_in LDO ground.
4 NC unconnected No internal connection.
5 EN input Enable input; a TTL high signal shuts the regulator down, and the EN voltage is limited to -0.3 V to VI + 0.3 V.
6 IN power_in Regulator input; recommended input voltage is 2.7 V to 10 V, with an absolute maximum of 13.5 V.
7 IN power_in Regulator input; recommended input voltage is 2.7 V to 10 V, with an absolute maximum of 13.5 V.
8 NC unconnected No internal connection.
9 GND/HSINK power_in Ground and heatsink pin.
10 GND/HSINK power_in Ground and heatsink pin.
11 GND/HSINK power_in Ground and heatsink pin.
12 GND/HSINK power_in Ground and heatsink pin.
13 OUT power_out Regulated output voltage; rated up to 1 A, with an output capacitor of at least 10 µF and ESR between 50 mΩ and 1.5 Ω required.
14 OUT power_out Regulated output voltage; rated up to 1 A, with an output capacitor of at least 10 µF and ESR between 50 mΩ and 1.5 Ω required.
15 FB/NC input Feedback input that senses the output voltage for the adjustable version (Vref = 1.1834 V typ); no connect on fixed-output options.
16 PG output Active-high open-drain power-good output that can implement a power-on reset or low-battery indicator, with a maximum PG voltage of 16.5 V.
17 NC unconnected No internal connection.
18 NC unconnected No internal connection.
19 GND/HSINK power_in Ground and heatsink pin.
20 GND/HSINK power_in Ground and heatsink pin.
21 Thermal pad passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TPS76801QPWPRQ1
  • Footprint: Package_SO:TSSOP-20-1EP_4.4x6.5mm_P0.65mm_EP2.15x3.35mm
  • 3D model: HTSSOP-20-EP, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.2 mm nominal TSSOP 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: tps76801qpwprq1-etched.step / tps76801qpwprq1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps76801qpwprq1.step / tps76801qpwprq1.glb are the bare package body.
