TPW4051-TR

3PEAK · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TSSOP-16

TPW4051-TR from 3PEAK, in a TSSOP-16. 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 A4 bidirectional Channel 4 analog input or output. Connects to common pin A when S2=H, S1=L, S0=L and /E=L.
2 A6 bidirectional Channel 6 analog input or output. Connects to common pin A when S2=H, S1=H, S0=L and /E=L.
3 A bidirectional Common analog input or output. Routed to one of A0-A7 based on the S0/S1/S2 select code when /E is low.
4 A7 bidirectional Channel 7 analog input or output. Connects to common pin A when S2=H, S1=H, S0=H and /E=L.
5 A5 bidirectional Channel 5 analog input or output. Connects to common pin A when S2=H, S1=L, S0=H and /E=L.
6 /E input Enable input, active low. When /E is HIGH all switches are turned off (high-impedance). When /E is LOW the channel selected by S0/S1/S2 is connected to A.
7 VEE power_in Negative power supply input. Typically tied to GND for single-supply operation or to a negative rail (e.g. -5V) for dual-supply operation. Analog signal range extends to the supplies.
8 GND power_in Ground / logic reference for the digital control inputs (S0, S1, S2, /E).
9 S2 input Digital channel-select input, MSB of the 3-bit address. Combined with S1 and S0 to select one of eight channels A0-A7.
10 S1 input Digital channel-select input, middle bit of the 3-bit address. Combined with S2 and S0 to select one of eight channels A0-A7.
11 S0 input Digital channel-select input, LSB of the 3-bit address. Combined with S2 and S1 to select one of eight channels A0-A7.
12 A3 bidirectional Channel 3 analog input or output. Connects to common pin A when S2=L, S1=H, S0=H and /E=L.
13 A0 bidirectional Channel 0 analog input or output. Connects to common pin A when S2=L, S1=L, S0=L and /E=L.
14 A1 bidirectional Channel 1 analog input or output. Connects to common pin A when S2=L, S1=L, S0=H and /E=L.
15 A2 bidirectional Channel 2 analog input or output. Connects to common pin A when S2=L, S1=H, S0=L and /E=L.
16 VCC power_in Positive power supply input. Supports 3.3V, 5V, 10V or +5V (with VEE=-5V). Maximum supply is 12V (VCC-VEE).

Two STEP files. Same geometry, different body top:

File Size Use it when
tpw4051-tr.step 205 KB You want the bare part, or you mark your own boards.
tpw4051-tr-etched.step 2.1 MB You want the part with TPW4051-TR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 546 faces against 255 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
