TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
TP2803E18-5 from TECH PUBLIC, 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 | VIN | power_in | Input supply voltage pin. Operating range 1.2V to 5.5V (absolute max 6.5V vs GND). A 1µF ceramic bypass capacitor to GND is recommended close to the pin. |
| 2 | GND | power_in | Device ground reference. Carries the ~2µA quiescent current and the internal reference return. |
| 3 | EN | input | Enable control input. Drive high (VIH ≥ 1.0V) to turn the regulator on; drive low (VIL ≤ 0.4V) to enter shutdown (~0.1µA typical). Absolute max -0.3V to 6V vs GND; input current typ 10nA at VEN=5V. |
| 4 | NC | unconnected | No internal connection. May be left floating or tied to GND for mechanical stability. |
| 5 | VOUT | power_out | Regulated output pin, fixed 1.8V ±2%, up to 400mA load. A 1µF ceramic (or tantalum) output capacitor to GND is required for stability. Absolute max -0.3V to 6V vs GND. |
