XC6211 Series Preliminary High Speed LDO Regulator Low ESR Cap. Compatible, On / Off Switch July 4, 2003 Ver. 3 Low Power Consumption Dropout Voltage Output Current : 25 µA (TYP) : 60mV (IOUT=30mA) 200mV (IOUT=100mA) : 150 mA (VOUT < 1.7V) 240 mA ( VOUT ≥ 1.8V) (300mA limit) Applications Mobile phones Cordless phones and radio communication equipment Portable games Cameras, Video recorders Reference Voltage Source Battery Powered Equipment Highly Accurate : ±2% (±30mV when VOUT=1.5V) Output Voltage Range : 0.9V ~ 5.0 V (50mV Step) Low ESR capacitor compatible General Description The XC6211 series are highly accurate, low noise, CMOS LDO Voltage Regulators. Offering low output noise, high ripple rejection ratio, low dropout and very fast turn-on times, the XC6211 series is ideal for today’s cutting edge mobile phone. Internally the XC6211 includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensators. The XC6211’s current limiters' foldback circuit also operates as a short protect for the output current limiter and the output pin. The output voltage is set by laser trimming. Voltages are selectable in 50mV steps within a range of 0.9V to 5.0V. The XC6211 series is also fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability. This high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of frequencies. The CE function allows the output of regulator to be turned off, resulting in greatly reduced power consumption. The XC6211 series is available in the SOT-23-5 package.
