SPX1117 800mA Low Dropout (LDO) Regulator ( Retail Price 1.6 Yuan including tax )
The SPX1117 is a low power forward voltage regulator that can be used in some high efficiency, small package low power designs. This device is very suitable for portable computers and battery-powered applications. The SPX1117 has a very low quiescent current, and its low dropout voltage is only 1.1V at full load. When the output current is reduced, the quiescent current varies with the load and improves efficiency. The SPX1117 is adjustable to select output voltages of 1.5V, 1.8V, 2.5V, 2.85V, 3.0V, 3.3V and 5V. ( Detailed introduction ) SP708 Low Power Microprocessor Peripheral Monitoring Device ( Retail Price 5.2 Yuan including tax )The SP708 series belongs to microprocessor (uP) monitoring devices, which integrate many components to monitor the power supply and battery operation in uP and digital systems. Due to the use of many of the above components, the SP708 series can effectively enhance the reliability and efficiency of the system. The SP708 series includes a watchdog timer, a uP reset module, a power failure comparator, and a manual reset input module. The SP708 series is suitable for developing computers, vehicle systems, controllers, and other intelligent instruments. For uP systems/digital processing systems with strict power supply requirements, the SP708 series is an ideal choice. ( Detailed introduction ) SP3243E Intelligent 3.0V~5.5V RS-232 Transceiver ( Retail price 8.3 yuan including tax )SP3243E is an RS-232 transceiver for portable or handheld applications such as laptops and PDAs. SP3243E uses an internal high-efficiency charge pump and only requires a 0.1uF capacitor to operate at a power supply voltage of 3.3V. This charge pump and Sipex driver structure allow the SP3243E series to send signals compatible with RS-232 characteristics at a voltage within the range of 3.3V~5.5V. SP3243E is a 3-driver/5-receiver device ideal for use in laptops and PDAs. The SP3243E includes an auxiliary receiver that can still alert the monitor through the external device's ring indicator when the device is in shutdown mode. ( Detailed Introduction ) SP3232E 3.0V to 5.5V RS-232 Transceiver ( Retail Price 8.1 Yuan including Tax )The SP3232E series is a solution for RS232 transceivers for portable or handheld applications such as notebooks or PDAs. The SP3232E series has a highly efficient charge pump that requires only 0.1μF capacitors for operation at a 3.3V operating voltage. The charge pump allows the SP3232E series to send RS-232 compliant signals at a voltage within 3.3V to 5.0V. The SP3232E series is a 2-driver/2-receiver device suitable for portable or handheld devices (such as notebooks or PDAs). ( Detailed introduction ) SP3485 3.3V low power half-duplex RS-485 transceiver ( retail price 10.4 yuan including tax )SP3485 is a series of 3.3V low power half-duplex transceivers, which fully meet the requirements of RS-485 and RS-422 serial protocols. These two devices are pin-compatible with Sipex's SP481, SP483 and SP485, and are compatible with industrial standard specifications. SP3485 complies with the electrical specifications of RS-485 and RS-422 serial protocols, and the data transmission rate can be up to 10Mbps (with load). ( Detailed introduction ) SC16IS752/SC16IS762 dual UART device with I ² C bus/SPI interface, 64-byte transmit and receive FIFO, built-in IrDA SC16IS752/SC16IS762 is an I ² C bus/SPI bus interface, dual-channel high-performance UART providing up to 5Mbit/s data rate, low operating and sleep current; it also provides applications with 8 additional programmable I/O pins. The device contains extremely small HVQFN32 and TSSOP28 packages, making it ideal for portable and battery-operated applications. ( Detailed introduction )
