MAS9130DA9130.002 28 January 2004 MAS9130 150 mA LDO Voltage Regulator IC Low Noise: 20 Vrms Low Minimum Output Capacitance Requirement: 0.22 F Excellent Ripple Rejection: 65 dB Very Low Dropout: 70 mV Regulator Enable/Disable Control Stable with Low-ESR Output Capacitors DESCRIPTION MAS9130 is a low dropout voltage regulator with an enable/disable pin, which allows device to be turned off or on by pulling control to low or high. Due to the low noise level of only 20 Vrms, MAS9130 is suitable for sensitive circuits, e.g., in portable applications. In addition to the noise levels, MAS9130 excels in dropout voltage (70 mV typical at 50 mA) and rise time (16 s typical without bypass capacitor). Also its ripple rejection ability of 65 dB at 10 kHz exceeds that of competition. The Equivalent Se……
