Changjing · Voltage Reference · SOT-23-5L

CJ6101B33M 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 power input, 1.8 V to 8 V (abs max 9 V). Bypass to VSS with a 1 µF ceramic capacitor close to the pin; a small series resistor (~3 Ω) may be added with an X5R ceramic to damp start-up transients.
2 VSS power_in Device ground / common return for VIN, VOUT and CE. All voltages in the datasheet are referenced to this node.
3 CE input Chip-enable logic input. On the 'B' option (CJ6101B) it is active-high with an internal pull-down resistor to VSS and an internal output-discharge resistor on VOUT, so leaving CE open keeps the regulator off. VCE(H) ≥ 1.5 V (up to VIN) enables the regulator; VCE(L) ≤ 0.3 V disables it (standby current ≈ 0.1 µA).
4 NC unconnected No internal connection. Leave floating or tie to VSS; do not use as a routing via.
5 VOUT power_out Regulated 3.3 V output, up to 300 mA continuous (600 mA absolute-max). Requires a 1 µF ceramic (or tantalum) capacitor to VSS close to the pin for loop stability; typical dropout is 110 mV at 100 mA and output noise ≈ 27 × VOUT µVRMS (10 Hz-100 kHz).
