APL3553ABI-TRG from Anpec Elec, in a SOT-23-5. 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 | VOUT | power_out | Output voltage pin that follows the input voltage; when the device is disabled it is discharged through an internal resistor (150 Ω typ.), and the absolute maximum VOUT-to-GND rating is -0.3 to 7 V. |
| 2 | GND | power_in | Ground pin; the negative pins of the input and output capacitors and this GND pin must be connected to the load ground plane. |
| 3 | OCB | output | Open-drain fault indication output that goes low after a 12 ms deglitch time when a current-limit or over-temperature condition is detected, and requires an external pull-up resistor. |
| 4 | EN | input | Active-high enable input for the APL3553A variant: a high level (VIH min. 1.4 V) enables the device and a low level (VIL max. 0.6 V) disables it, and the pin cannot be left floating. |
| 5 | VIN | power_in | Power supply input connected to the external DC supply, with a recommended operating range of 2.7 V to 5.5 V and an absolute maximum of 7 V. |
