Overview
The BU33TD2WNVX-TL is a high-precision, fixed-output CMOS LDO (Low Dropout) Voltage Regulator from ROHM Semiconductor, designed to deliver a stable 3.3V output from an input voltage range of 1.7V to 6V. Capable of supplying up to 200 mA of output current, this regulator features a low dropout voltage of 220 mV (typical) and an excellent 70 dB PSRR, making it ideal for noise-sensitive power rails. Housed in a compact DFN-4 package, the device supports SMD mounting and operates reliably across a temperature range of -40°C to +85°C. With a quiescent current of only 35 µA and a voltage regulation accuracy of ±1%, it is well-suited for battery-powered and portable applications where power efficiency and space constraints are critical.
Features
- High Accuracy Output: ±1% voltage regulation tolerance ensures stable 3.3V output for precision analog and digital circuits.
- Ultra-Low Quiescent Current: Typical 35 µA operating supply current significantly extends battery life in portable devices.
- Excellent Ripple Rejection: 70 dB PSRR at typical conditions effectively filters noise from switching power supplies or input lines.
- Wide Input Voltage Range: Supports input from 1.7V to 6V, compatible with single-cell Li-ion batteries and standard 3.3V/5V rails.
- Low Dropout Voltage: 220 mV typical dropout at 200 mA load minimizes power dissipation and allows operation near the output voltage.
Pin Configuration and Functions
- Pin1: VIN - Input voltage supply pin. Connect to a 1.7V to 6V power source with a bypass capacitor close to the pin.
- Pin2: GND - Ground reference pin. Connect directly to the system ground plane for stable operation.
- Pin3: EN - Enable control pin. Drive high to enable the regulator; connect to VIN if not used.
- Pin4: VOUT - Regulated 3.3V output pin. Connect to the load with an output capacitor for stability.
Typical Applications
- Battery-Powered IoT Sensors: Provides a stable 3.3V rail for microcontrollers and RF modules while minimizing battery drain.
- Portable Medical Devices: Low noise and high PSRR ensure clean power for sensitive analog front-end circuits.
- Wearable Electronics: Compact DFN-4 package and low quiescent current suit space-constrained, always-on devices.
- Camera Modules: Delivers precise 3.3V to image sensors, reducing ripple from the main system power bus.
- Industrial Control Interfaces: Reliable regulation for MCU and logic power in 3.3V industrial sensor nodes.
Equivalent / Alternative Parts
- BU33TD2WNVX (ROHM Semiconductor): Same die and package; identical electrical specifications, used as a direct substitute.
- BD33IC0MEFJ-M (ROHM Semiconductor): Alternative 3.3V LDO with similar dropout and current rating, but in a different HTSOP-J8 package.
Design-in Tips
- Input/Output Capacitor Selection: Use a 1 µF ceramic capacitor on both VIN and VOUT pins, placed as close as possible to the package for stability and transient response.
- Thermal Management: The DFN-4 package has a power dissipation limit of 560 mW. Ensure adequate PCB copper area for heat sinking when operating near maximum load and high input voltage.
- Enable Pin Handling: If the EN pin is not used, connect it directly to VIN to ensure the regulator is always active; avoid leaving it floating.
