S-1200B33-M5T1U

ABLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

S-1200B33-M5T1U from ABLIC, in a SOT-23-5. 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 Input voltage pin. Absolute maximum VSS−0.3 V to VSS+12 V; operating range 2.0 V to 10.0 V. A ceramic input capacitor of 0.1 µF or more should be connected between VIN and VSS.
2 VSS power_in Ground (GND) reference pin for the regulator.
3 ON/OFF input ON/OFF control input. For the 'B' product type (positive logic, this MPN), driving the pin high (VSH ≥ 1.5 V) enables the regulator and driving it low (VSL ≤ 0.25 V) disables it (ISS ≈ 0.01 µA in OFF). Absolute maximum VSS−0.3 V to VIN+0.3 V; input current ±0.1 µA typ.
4 NC unconnected No-connection pin. Electrically open inside the package. May be left floating or tied to VIN or VSS.
5 VOUT power_out Regulated output voltage pin (3.3 V ±1.0% for the -B33 option). Delivers up to 150 mA when VIN ≥ VOUT(S)+1.0 V; short-circuit current limited to ~250 mA by the built-in overcurrent protection. Requires 0.1 µF or larger ceramic output capacitor to VSS.
