TPS77733PWPR

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

TPS77733PWPR 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/heatsink terminal of the PowerPAD package, one of eight GND/HSINK pins.
2 GND/HSINK power_in Ground/heatsink terminal of the PowerPAD package, one of eight GND/HSINK pins.
3 GND power_in Regulator ground.
4 NC unconnected No connect.
5 EN input Enable input; applying a TTL high signal shuts down the regulator into sleep mode.
6 IN input Input voltage to the regulator.
7 IN input Input voltage to the regulator.
8 NC unconnected No connect.
9 GND/HSINK power_in Ground/heatsink terminal of the PowerPAD package, one of eight GND/HSINK pins.
10 GND/HSINK power_in Ground/heatsink terminal of the PowerPAD package, one of eight GND/HSINK pins.
11 GND/HSINK power_in Ground/heatsink terminal of the PowerPAD package, one of eight GND/HSINK pins.
12 GND/HSINK power_in Ground/heatsink terminal of the PowerPAD package, one of eight GND/HSINK pins.
13 OUT output Regulated output voltage; an output capacitor of at least 10 µF is required between OUT and GND for stability.
14 OUT output Regulated output voltage; an output capacitor of at least 10 µF is required between OUT and GND for stability.
15 FB/NC input Feedback input for the adjustable version; no connect for the fixed-output TPS77733.
16 RESET output Open-drain RESET output that signals an undervoltage on the regulated output after a 200 ms delay.
17 NC unconnected No connect.
18 NC unconnected No connect.
19 GND/HSINK power_in Ground/heatsink terminal of the PowerPAD package, one of eight GND/HSINK pins.
20 GND/HSINK power_in Ground/heatsink terminal of the PowerPAD package, one of eight GND/HSINK pins.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TPS77733PWPR
  • 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: tps77733pwpr-etched.step / tps77733pwpr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps77733pwpr.step / tps77733pwpr.glb are the bare package body.
