SSP9193-33M5R from Shanghai Siproin Microelectronics, 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 | Power input voltage. Recommended operating range 2.5V to 5.5V. Bypass to GND with a 1uF (X7R) ceramic capacitor placed close to the pin. |
| 2 | GND | power_in | Device ground reference. Common return for VIN, VOUT, EN and BP. |
| 3 | EN | input | Chip Enable (active high). VIH >= 1.2V enables the regulator; VIL <= 0.4V shuts it down (standby <0.01uA typ). High-impedance input; must not float - tie to VIN or via a 100k pull-down to GND. EN input voltage range 0V to 5.5V. |
| 4 | BP | passive | Reference noise bypass. May be left floating; for lowest output noise (100uVRMS) connect a 22nF ceramic capacitor from BP to GND. |
| 5 | VOUT | power_out | Regulated output voltage. Factory-trimmed to 3.3V (±2%) for the -33 option. Output current capability 400mA typ / 500mA max (Vin-Vout=1V). Requires a >=1uF (X7R) ceramic output capacitor to GND placed close to the pin for phase compensation. |
