# TPS7B6701QPWPRQ1

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

TPS7B6701QPWPRQ1 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 | RESET | output | Output ready signal with open-drain configuration, pulled low (VOL ≤ 0.4V at IOL = 0.5mA) when regulated output voltage falls below 89.6% of set value after 55-420µs deglitch delay. |
| 2 | NC | unconnected | Not connected. |
| 3 | DELAY | output | Reset pulse delay adjustment pin; external capacitor (100pF to 500nF) connected to GND sets power-on-reset delay time with constant charging current 6-14µA (typical 9.5µA) until 1V threshold. |
| 4 | VOUT | power_out | Regulated output voltage for adjustable version (1.5V to 18V), regulated within ±2% from input 4V-40V, maximum output current 450mA with 160-450mV dropout voltage depending on load. |
| 5 | ADJ | input | Feedback pin for output voltage adjustment, connected to 1.233V ± 2% bandgap reference through external resistor divider to set VOUT from 1.5V to 18V; maximum absolute voltage 22V, divider sum (R1+R2) 10kΩ-100kΩ. |
| 6 | NC | unconnected | Not connected. |
| 7 | NC | unconnected | Not connected. |
| 8 | GND | power_in | Ground reference pin for return current path. |
| 9 | NC | unconnected | Not connected. |
| 10 | NC | unconnected | Not connected. |
| 11 | NC | unconnected | Not connected. |
| 12 | NC | unconnected | Not connected. |
| 13 | GND | power_in | Ground reference pin for return current path. |
| 14 | NC | unconnected | Not connected. |
| 15 | EN | input | Enable input with high-voltage tolerance to 40V; logic high (≥1.7V) activates regulator, logic low (≤0.4V) disables regulator reducing quiescent current to <4µA. |
| 16 | NC | unconnected | Not connected. |
| 17 | NC | unconnected | Not connected. |
| 18 | NC | unconnected | Not connected. |
| 19 | VIN | power_in | Input power-supply voltage with operating range 4V to 40V (absolute maximum 45V transient), UVLO threshold 2.6V with 1V hysteresis; bypass capacitors (47µF electrolytic and 0.1µF ceramic) recommended. |
| 20 | NC | unconnected | Not connected. |
| 21 | PowerPAD | passive | Exposed thermal pad for heat dissipation; solder to enhanced copper area on PCB for improved thermal performance with junction-to-ambient thermal resistance 44.9°C/W and junction-to-board 23.6°C/W. |

## CAD (KiCad official)

- Symbol: `TPS7B6701QPWPRQ1`
- 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: `tps7b6701qpwprq1-etched.step` / `tps7b6701qpwprq1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps7b6701qpwprq1.step` / `tps7b6701qpwprq1.glb` are the bare package body.
