# LP3470A365DBVR

**Texas Instruments** · Supervisor And Reset ICs · SOT-23-5

LP3470A365DBVR 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 | SRT | input | Set reset time-out pin: connect a capacitor between this pin and GND to set the reset time-out period, tD = 619 × C(SRT) (C in µF, tD in ms), and leave it floating if no capacitor is used. |
| 2 | GND | power_in | Ground pin. |
| 3 | VCC1 | input | Can be connected to VCC or left floating, and must not be connected to GND. |
| 4 | VCC | power_in | Supply voltage and reset threshold monitor input, specified for 0.95 V to 10 V (absolute maximum 12 V). |
| 5 | RESET | output | Open-drain, active-low reset output that requires an external pullup resistor; it goes low when VCC falls below VIT-, and after VCC exceeds VIT- + VHYS it stays low for the time-out period tD before going high, with RESET pin voltage limited to 0 to 10 V and pin current to ±5 mA. |
