# LP3470IM5-2.93

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

LP3470IM5-2.93 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 | output | Set reset time-out pin: connect a capacitor to ground to set tRP = 2000 × C1 (C1 in µF, tRP in ms), or leave it floating if no reset delay is needed. |
| 2 | GND | power_in | Ground pin. |
| 3 | VCC1 | input | Must always be connected to pin VCC (pin 4). |
| 4 | VCC | power_in | Supply voltage and reset threshold monitor input, with a recommended operating range of 0.5 V to 5.5 V and an absolute maximum of 6 V. |
| 5 | Reset | output | Open-drain, active-low reset output that requires an external pullup resistor (0.68 kΩ to 68 kΩ) and goes low when VCC falls below the reset threshold VRTH. |
