# TPS7A1601DRBR

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SON-8-EP(3x3)

TPS7A1601DRBR from Texas Instruments, in a SON-8-EP(3x3). 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 | OUT | output | Regulator output pin; a capacitor ≥ 2.2 µF must be tied from this pin to ground to assure stability. |
| 2 | FB/DNC | input | For adjustable version TPS7A1601, feedback pin is input to control-loop error amplifier; for fixed versions, do not connect. |
| 3 | PG | tri_state | Power-good open collector output; leave open or connect to GND if power-good function is not needed. |
| 4 | GND | power_in | Ground pin. |
| 5 | EN | input | Enable pin that turns regulator on when VEN ≥ VEN_HI and off when VEN ≤ VEN_LO. |
| 6 | NC | unconnected | No-connect pin; can be left open or tied to any voltage between GND and IN. |
| 7 | DELAY | output | Delay pin; connect a capacitor to GND to adjust PG delay time, or leave open if reset function is not needed. |
| 8 | IN | power_in | Regulator input supply pin; a capacitor ≥ 0.1 µF must be tied from this pin to ground to assure stability. |
| 9 | PowerPAD | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
