TPS76818QPWPR

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

TPS76818QPWPR from Texas Instruments, in a HTSSOP-20. 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 Regulator ground and heatsink connection.
2 GND/HSINK power_in Regulator ground and heatsink connection.
3 GND power_in Regulator ground.
4 NC unconnected No connect; no internal connection.
5 EN input Enable input; a TTL high signal shuts the regulator down, with high-level input threshold of 1.7 V and low-level threshold of 0.9 V.
6 IN power_in Input voltage; recommended range 2.7 V to 10 V, with absolute maximum input of 13.5 V.
7 IN power_in Input voltage; recommended range 2.7 V to 10 V, with absolute maximum input of 13.5 V.
8 NC unconnected No connect; no internal connection.
9 GND/HSINK power_in Regulator ground and heatsink connection.
10 GND/HSINK power_in Regulator ground and heatsink connection.
11 GND/HSINK power_in Regulator ground and heatsink connection.
12 GND/HSINK power_in Regulator ground and heatsink connection.
13 OUT power_out Regulated output voltage; output current range 0 to 1.0 A.
14 OUT power_out Regulated output voltage; output current range 0 to 1.0 A.
15 FB/NC input Feedback input voltage for the adjustable device; no connect for fixed-output options such as the TPS76818.
16 PG output Open-drain power-good output that pulls low when VO falls to between 92% and 98% of nominal and requires an external pullup resistor.
17 NC unconnected No connect; no internal connection.
18 NC unconnected No connect; no internal connection.
19 GND/HSINK power_in Regulator ground and heatsink connection.
20 GND/HSINK power_in Regulator ground and heatsink connection.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TPS76818QPWPR
  • Footprint: Package_SO:TSSOP-20-1EP_4.4x6.5mm_P0.65mm_EP2.15x3.35mm
  • 3D model: HTSSOP-20, 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: tps76818qpwpr-etched.step / tps76818qpwpr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps76818qpwpr.step / tps76818qpwpr.glb are the bare package body.
