XC9236A33CMR-G from Torex Semicon, in a SOT-25-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Power input with an operating range of 2.0V to 6.0V for A-type devices and an absolute maximum rating of -0.3V to 6.5V; a bypass capacitor CIN should be placed as close as possible to the VIN and VSS pins. |
| 2 | VSS | power_in | Ground pin that should be shorted to the other VSS pin on the package (the USP variants use pins 2 and 5), and the datasheet gives no separate electrical limit for it. |
| 3 | CE/MODE | input | High-active enable pin: H level is VIN - 0.65V ≤ H ≤ 6.0V and L level is 0V ≤ L ≤ 0.25V for the XC9236 series, and the pin must not be left open. |
| 4 | VOUT | power_out | Fixed output voltage pin for A/B/C/E/G types, which in the A33 device is the 3.3V regulated output, with an absolute maximum rating of -0.3V to 6.5V. |
| 5 | Lx | output | Switching output pin driven by the internal P-channel and N-channel driver transistors, with an absolute maximum voltage of -0.3V to VIN + 0.3V and a pin current limit of ±1500 mA. |
