MCP1703A

MCP1703A是MCP1703低压差(LDO)稳压器的改进版本，可提供高达250 mA的电流，同时仅消耗2.0 μ A的静态电流(典型)。输入工作范围从2.7V到16.0V指定，使其成为两到六个主电池电池供电应用，9V碱性和一个或两个电池锂离子供电应用的理想选择。MCP1703A能够提供250 mA，只有625 mV(典型)的输入输出电压差(VOUT = 2.8V)。MCP1703A的输出电压容差在+25℃时通常为±0.4%，在-40℃至+125℃的工作结温范围内，最大输出电压容差为±3%。在+25°C时，线路调节为±0.1%。MCP1703A的输出电压范围从1.2V到5.5V。仅使用1µF的输出电容时，LDO输出稳定。陶瓷、钽或铝电解电容器均可用于输入和输出。过流限制和过温关断为任何应用提供了强大的解决方案。套件选项包括SOT-223-3, SOT-23A, 2x3 DFN-8和SOT-89-3。MCP1703A通过AEC-Q100汽车应用认证。

The MCP1703A is an improved version of the MCP1703 Low Voltage Difference (LDO) regulator that delivers up to 250 mA while consuming only 2.0 μA of static current (typical). The input operating range is specified from 2.7V to 16.0V, making it ideal for two to six main battery battery-powered applications, 9V alkaline and one or two battery Li-ion powered applications. The MCP1703A is capable of delivering 250 mA with only 625 mV(typical) input-output voltage difference (VOUT = 2.8V). The output voltage tolerance of the MCP1703A is usually ±0.4% at +25 ° C, and the maximum output voltage tolerance is ±3% over the operating junction temperature range of -40 ° C to +125 ° C. At +25°C, the line is adjusted to ±0.1%. The output voltage of the MCP1703A ranges from 1.2V to 5.5V. The LDO output is stable when only 1µF of output capacitance is used. Ceramic, tantalum or aluminum electrolytic capacitors can be used for both input and output. Overcurrent limiting and overtemperature shut-off provide a powerful solution for any application. Kit options include the SOT-223-3, SOT-23A, 2x3 DFN-8 and SOT-89-3. The MCP1703A is certified for AEC-Q100 automotive applications.
