LP3470A438DBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SRT | input | Reset timeout control input; connect a capacitor between this pin and ground to program reset delay period (tD = 619 × C₁ ms, where C₁ in µF), or leave floating for minimum 50 µs timeout. |
| 2 | GND | power_in | Ground reference and power return path. |
| 3 | VCC1 | input | Auxiliary supply pin that may be connected to VCC or left floating (do not connect to ground). |
| 4 | VCC | power_in | Main supply voltage input (0.95 V to 10 V) monitored to generate reset signal when voltage falls below negative-going threshold (VIT-). |
| 5 | RESET | tri_state | Open-drain active-low reset output that asserts low when VCC drops below VIT- and remains asserted for the programmed delay period (tD) after VCC exceeds VIT- plus hysteresis (VHYS). |
