Vg3.3 -

| Parameter | Typical Value | Importance | |-----------|---------------|-------------| | Input Voltage Range | 4.5V to 28V (LDOs may go to 16V; switching regs go higher) | Determines what power source you can use. | | Output Voltage | 3.3V ± 1% to ± 3% | Precision affects downstream logic thresholds. | | Maximum Output Current | 150mA to 3A (depending on package) | Defines how many components you can power. | | Dropout Voltage (LDO) | 100mV to 500mV at full load | Critical for battery applications (e.g., 3.6V input → 3.3V output). | | Quiescent Current (IQ) | 20µA to 2mA | Extremely important for battery-powered sleep modes. | | Ripple (Switching Reg) | 20mV to 50mV peak-to-peak | Affects analog and RF performance. | | Load Regulation | < 1% | Ensures voltage stays stable as current draw changes. | | Line Regulation | < 0.1% | Keeps output steady as input voltage fluctuates. | | Operating Temp Range | -40°C to +125°C | Industrial and automotive applications. |

: The VG33E pump is generally superior to older VG30 models, though it may require minor modifications (like to the crankshaft snout) if being used in certain swap scenarios. High-Compression Modifications : Shaving the heads (around ) can yield a compression increase of approximately | Parameter | Typical Value | Importance |

However, in many technical datasheets and engineering forums, VG3.3 is shorthand for a specific class of low-dropout regulators (LDOs) or switching regulators designed to convert higher input voltages (such as 5V, 9V, or 12V) down to a clean 3.3V rail. It has become the de facto standard power supply for microcontrollers, FPGAs, and low-power wireless chips. | | Dropout Voltage (LDO) | 100mV to

The standard originated in German industrial engineering (VDMA – Mechanical Engineering Industry Association) but has since been adopted globally. VG3.3 harmonizes older conflicting standards (such as the original VG1.0 and VG2.2) into a single, unambiguous framework. | | Load Regulation | &lt; 1% |
