TPS3801-01DCKR from Texas Instruments, in a SC-70-5. 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 | GND | power_in | Device ground reference. All voltages are measured with respect to GND. Pin 1 and pin 2 are internally connected and both should be tied to the ground plane. |
| 2 | GND | power_in | Device ground reference (second GND pin, internally common with pin 1). Tie to the ground plane. |
| 3 | RESET | output | Active-low push-pull reset output. Driven low during power-up, and whenever SENSE falls below the 1.14 V internal reference; remains asserted for the 200 ms fixed reset delay (t_d = 120-280 ms) after SENSE returns above threshold. V_OH = V_DD - 0.4 V at I_OH = -2 mA (V_DD = 3.3 V); V_OL = 0.4 V at I_OL = 2 mA. |
| 4 | VDD | power_in | Device supply voltage. Recommended operating range 1.6 V to 4 V (absolute max 7 V). Quiescent current typically 7 uA at V_DD = 1.6 V (SENSE = 0 V) rising to 9 uA at V_DD = 4 V. Place a 0.1 uF bypass capacitor close to this pin for best threshold stability. |
| 5 | SENSE | input | Adjustable-threshold sense input. Compared internally against a 1.14 V reference; RESET is asserted low when SENSE < V_ref. Use an external resistor divider from the monitored rail to set the trip point: V_trip = 1.14 V x (1 + R1/R2). Input current is typically +/-25 nA over -0.3 V to 5 V; minimum SENSE pulse width to trigger RESET is 1 us. |
