Battery-powered equipment Voltage regulator for microprocessor Voltage regulator for LAN cards Wireless Communication equipment Audio/Video equipment

The HT73XX series is a set of three-terminal, low power, high voltage regulators implemented in CMOS technology. The series features extremely low quiescent current which is typically 4mA. They allow input voltages as high as 12V. The device provides large current with a significantly small dropout voltage. The HT73XX consists of a high-precision voltage reference, an error correction circuit, and a current limited output driver. They are available with several fixed output voltages ranging from to 5.0V. CMOS technology ensures low dropout voltage and low current consumption. Although designed primarily as fixed voltage regulators, these devices can be used with external components to generate variable voltages and currents.

  MP2307 3A / 23V 340KHz Synchronous Rectifier Buck Converter 3.3V Adjustable Winder

   

  The MP2307 is a monolithic synchronous buck regulator. The device integrates 100mΩ MOSFETS that provide 3A of continuous load current over a wide operating input voltage of 4.75V to 23V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn-on and in shutdown mode, the supply current drops below 1µA. This device, available in an 8-pin SOIC package, provides a very compact system solution with minimal reliance on external components.

• Output Voltage: 3.3V
• Output Current: 800mA
• Dropout Voltage: 1V

   3. Set two data transmission indicators to monitor the data transmission status in real time
   4. Brush 3.3V and 5V pin interface, convenient for different voltage system machines that need power supply
   5. The interface pin header is parallel to the board, instead of being installed perpendicular to the board, which is convenient for the DuPont line when flashing.
   6. The entire circuit board is covered with transparent heat-shrinkable tubing, so that the PCB circuit board and the entity form an independent state, thereby protecting the board metal from sudden explosion and burning. Due to the use of transparent materials, there is no interface for screen silk screen viewing and indicator monitoring effects
