CJ6101B18M from Changjing, in a SOT-23-5L. 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 | Unregulated positive supply input. Operating range 1.8 V to 8 V (abs-max -0.3 V to +9 V). Bypass with a 1 μF ceramic or tantalum capacitor close to the pin; series 3 Ω recommended with X5R MLCC to damp start-up transients. |
| 2 | VSS | power_in | Device ground / signal return. All voltages in the datasheet are referenced to this pin. Tie directly to the ground plane and to the negative terminal of CIN and COUT. |
| 3 | CE | input | Chip Enable, active-high on the 'B'-designator variant (VCE_H ≥ 1.5 V, VCE_L ≤ 0.3 V). 'B' option integrates a CE pull-down resistor so the pin defaults to disabled if left floating; drive high to enable the regulator. Standby current with CE=VSS is 0.1 μA typ. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to VSS for best PCB stability; do not use as a routing via. |
| 5 | VOUT | power_out | Regulated output, factory-trimmed to 1.8 V on this MPN (accuracy ±2 % / ±1 % typ.). Delivers up to 300 mA continuous; current limit 550-850 mA (typ 700 mA). Requires a ≥1 μF output capacitor to VSS for loop stability; ceramic COUT improves transient response. |
