ITEM NAME:5X 5V to 3.3V DC-DC Step-Down Power Supply Buck Module Board AMS1117 LDO 800MA Descriptio n Description: AMS1117-3.3 is a positive Voltage Regulator Step Down Power Supply Module, support DC 4.5-7V input and 3.3V fixed voltage and 0.8A current output. The module is suitable for electronic devices such as SCM project design needs 3.3V power supply, It is simple Dual-panel design and the Input output using the 2 Pin single row pin for easy connection. AMS1117-3.3 pinout can be easy to connected with your MCU development and provide the contant power supply. Applicable for high-efficiency linear regulator Published Active Power Regulator Battery Charger Active instrument. Applications: Arduino MEGA2560; MSP430 Development Board; 3.3V Low power consumption MCU; FPGA/CPLD PLD Programmable Logic Systems; ARM7 ARM9 ARM11 STM32; etc. AMS1117 overheat shutdown circuit provides overload and over-temperature protection. Attention : 1: Boost modules or buck module indicate the operating voltage, Please donot exceed operating voltage , or it will be damaged easily ! 2: Boost module output voltage can only be greater than or equal to input voltage, cannot be less than the input voltage! 3: Buck module input voltage must be higher than output voltage of 1.5V or 2V, otherwise it can not output enough power! 4: Automatic Adjustable Boost or Buck module has start voltage and limit working voltage, Please donot exceed them , or it will be damaged easily ! 5: Cannot reverse polarity , or it will be short circuit, or will be born easily ! Specifications: 1: Input: DC 4. 5V-7V (Input Voltage Must Be More Than To Output Voltage High 1V Above.) 2: Output: 3.3V, 800mA (Load Current Can'T More Than 800 mA) 3: PCB Size: 8.6* 12.3 mm Package Included: 5 *Â Step-Down Power Supply Modules Note: 1.Due to the manual measurement and different measurement methods, the actual size could be slightly different. 2.Please be reminded that due to lighting effects and monitor's brightness/contrast.AMS1117 overheat shutdown circuit provides overload and over-temperature protection. 2: Output: 3.3V, 800mA (Load Current Can'T More Than 800 mA). Specifications:1: Input: DC 4. We'd like to settle any problem in a friendly manner.
