TPS70702PWPR 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 | NC | unconnected | No connection; the datasheet lists this pin as not connected internally. |
| 2 | VIN1 | power_in | Input voltage of regulator 1; internal bias voltages are powered from VIN1, and the UVLO circuit keeps the regulators off until VIN1 reaches 2.5 V. |
| 3 | VIN1 | power_in | Input voltage of regulator 1; internal bias voltages are powered from VIN1, and the UVLO circuit keeps the regulators off until VIN1 reaches 2.5 V. |
| 4 | MR1 | input | Manual reset input 1, active low, with an internal 6-µA pull-up to VIN1; pulling it low triggers a POR (RESET). |
| 5 | MR2 | input | Manual reset input 2, active low, with an internal 6-µA pull-up to VIN1; pulling it low triggers a POR (RESET). |
| 6 | EN | input | Active-low enable; a high level puts both regulators in sleep mode (input current about 1 µA at TJ = +25°C) and a low level enables the device. |
| 7 | SEQ | input | Power-up sequence control: high or open makes VOUT2 power up first, low makes VOUT1 power up first; the pin has an internal 6-µA pull-up to VIN1. |
| 8 | GND | power_in | Ground connection for the device. |
| 9 | VIN2 | power_in | Input voltage of regulator 2. |
| 10 | VIN2 | power_in | Input voltage of regulator 2. |
| 11 | NC | unconnected | No connection; the datasheet lists this pin as not connected internally. |
| 12 | VOUT2 | power_out | Output voltage of regulator 2, which can supply up to 125 mA. |
| 13 | VOUT2 | power_out | Output voltage of regulator 2, which can supply up to 125 mA. |
| 14 | VSENSE2/FB2 | input | Regulator 2 output sense for fixed-voltage versions (connect as close as possible to VOUT2) or feedback input for the adjustable version, which must connect to the external feedback divider. |
| 15 | RESET | output | Open-drain active-low power-on reset output that indicates VOUT2 and MR1/MR2 status; it goes high-impedance 120 ms after VOUT2 exceeds 95% of its regulated voltage and requires a pull-up resistor. |
| 16 | PG1 | output | Open-drain power-good output for regulator 1 that goes high-impedance when VOUT1 reaches 95% of its regulated voltage and low when it falls below that level; it requires a pull-up resistor. |
| 17 | VSENSE1/FB1 | input | Regulator 1 output sense for fixed-voltage versions (connect as close as possible to VOUT1) or feedback input for the adjustable version, which must connect to the external feedback divider. |
| 18 | VOUT1 | power_out | Output voltage of regulator 1, which can supply up to 250 mA. |
| 19 | VOUT1 | power_out | Output voltage of regulator 1, which can supply up to 250 mA. |
| 20 | NC | unconnected | No connection; the datasheet lists this pin as not connected internally. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
