# AP2104BTCER

**Wuxi Chipown Micro electronics** · Charge Pumps · SOT-23-6L

AP2104BTCER from Wuxi Chipown Micro electronics, in a SOT-23-6L. 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 | VOUT | output | Output voltage requiring at least 2.2µF low ESR ceramic capacitor placed close to pin for best performance. |
| 2 | GND | power_in | Power ground connection. |
| 3 | EN | input | Low voltage shutdown input with approximately 0.8V threshold; pin must not float and requires valid logic level drive. |
| 4 | C- | passive | Bootstrap capacitor negative terminal requiring low ESR ceramic capacitor minimum 2.2µF; do not use polarized aluminum or tantalum capacitors. |
| 5 | VIN | power_in | Input power supply voltage (2.7V to 5.5V) requiring at least 2.2µF low ESR ceramic capacitor placed close to pin for best performance. |
| 6 | C+ | passive | Bootstrap capacitor positive terminal requiring low ESR ceramic capacitor minimum 2.2µF; do not use polarized aluminum or tantalum capacitors. |
