TPBL9198-33BAPRN 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 | Supply input to the LDO. Operating range up to 6 V absolute max; typical operation Vout+1 V up to 5.5 V. Bypass to GND with a 1 uF (up to 10 uF) ceramic capacitor placed close to the pin. |
| 2 | GND | power_in | Device ground reference. Connect to the system ground plane with a low-impedance return path. |
| 3 | CE | input | Chip enable (active-high) with external pull-down (BA option). Drive high to enable the regulator; drive low (or 0 V) to place the device in shutdown (<1 uA standby). Do not leave floating. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to GND for mechanical robustness. |
| 5 | VOUT | power_out | Regulated output. For the -33 option, Vout = 3.3 V typical, 300 mA max output current, ~90 mV dropout at 100 mA. Requires a 1 uF (up to 10 uF) ceramic output capacitor to GND for stability. |
