ME6231 Datasheet | ChipSourceTek

ME6231 18V, Low Power, High Accuracy, High PSRR LDO Regulators Description Feature The ME6231 series are high accuracy, CMOS LDO - Maximum Output Current: 500mA Voltage Regulators, offering low power, high ripple （VIN＝4.3V,VOUT＝3.3V） rejection ratio and low dropout. the ME6231 series is - Dropout Voltage: 125mV@IOUT =100mA（VOUT＝ ideal for today’s cutting edge mobile phone. Internally 3.3V） the ME6231 includes a reference voltage source, error - Operating Voltage Range: 3V~18V amplifiers, driver transistors, current limiters and phase - Output Voltage Range: 1.6V~5.0V pensators. The ME6231’s current limiters' foldback - Highly Accuracy: ±1％ 技 circuit also operates as a short protect for the output - Low Power Consumption: 1.8uA（TYP.） k current limiter and the output pin. The ME6231 series is - Standby Current: 0 uA（TYP.） 科 e also fully patible with low ESR ceramic capacitors, - High Ripple Rejection: 65dB@1KHz（ME6231C33） 特 T reducing cost and improving output stability. This high - Line Regulation: 0.035％/V（TYP.） e level of output stability is maintained even during - Built-in temperature protection and current limiting 源 rc frequent load fluctuations, due to the excellent transient protection 矽 u response performance and high PSRR achieved across o a broad range of frequencies. The CE function allows the output of regulator to be turned off, resulting in S greatly reduced power consumption.
