TPS7A20185PDBVR from Texas Instruments, in a SOT-23-5. 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 | IN | power_in | Input voltage supply from 1.6V to 6.0V; use nominal value or larger capacitor from IN to ground as listed in Recommended Operating Conditions; place input capacitor as close to IN and GND pins as possible for best transient response and minimum input impedance. |
| 2 | GND | power_in | Common ground. |
| 3 | EN | input | Enable input; active high; voltage less than VEN(LOW) 0.3V turns regulator off and discharges output to GND; voltage greater than VEN(HI) 0.9V enables regulator output; has internal 500kΩ pulldown resistor to hold regulator off by default. |
| 4 | N/C | unconnected | No internal electrical connection. |
| 5 | OUT | output | Regulated output voltage from 0.8V to 5.5V; low ESR capacitor required from OUT to ground for stability; minimum 1µF recommended; internal 150Ω typical pulldown resistor prevents charge remaining on VOUT in shutdown mode; place output capacitor as close to OUT and GND pins as possible. |
