| Parameter | Likely Value / Range | Notes | | :--- | :--- | :--- | | | Positive Voltage Regulator / DC-DC Converter Controller | Many KZ-prefix parts serve as linear regulators. | | Output Voltage (Vout) | Fixed: 3.3V, 5.0V, or 12V | The “033” in 12033 might hint at 3.3V or a 33V output (rare). More likely 3.3V. | | Output Current (Iout) | Up to 1A (or 500mA) | Typical for TO-252 or SOT-223 packages. | | Input Voltage (Vin) | 4.5V to 35V (for 3.3V out) | Standard for linear regulators. | | Dropout Voltage | 2V typical (standard) or Low-Dropout (LDO) ~0.5V | Depends on internal design. | | Package Type | TO-252 (DPAK), SOT-223, or SOP-8 | Surface-mount packages are most common. | | Operating Temp | -40°C to +85°C (Industrial) | Could extend to +125°C. | | Protection Features | Overcurrent, Overtemperature, Short-circuit | Standard for voltage regulators. | kz12033a1
