1 / 18 page Data Sheet 1 R000026 XC6219 Series High Speed LDO Regulators, Low ESR Cap. Compatible, ON/OFF Switch October 4, 2004 V5 CMOS Low Power Consumption APPLICATIONS Dropout Voltage 60mV @ 30mA Mobile phones 200mV @ 100mA Cordless phones and radio communication equipment Output Current 150mA (VOUT<1.75V) Portable games 240mA (VOUT>1.8V) Cameras, video cameras (300mA limit) Reference voltage sources Highly Accurate + 2% Battery powered equipment (+30mV when VOUT>1.5V) Output Voltage Range 0.9V to 5.0V (50mV increments) Low ESR Ceramic Capacitor Compatible GENERAL DESCRIPTION FEATURES The XC6219 series are highly accurate, low noise, CMOS LDO Maximum Output Current 150mA (VOUT<1.75V) Voltage Regulators. Offering low output noise, high ripple rejection 240mA (VOUT>1.8V) ratio, low dropout and very fast turn-on times, the XC6219 series (300mA limit (TYP)) is ideal for today’s cutting edge mobile phone. Dropout Voltage 200mV (IOUT=100mA) Internally the XC6219 includes a reference voltage source, error Operating Voltage Range 2.0V ~ 6.0V amplifiers, driver transistors, current limiters and phase Output Voltage Range 0.9V ~ 5.0V (50mV steps) compensators. The XC6219’s current limiters' foldback circuit Highly Accurate + 2% (VOUT>1.5V) also operates as a short protect for the output current limiter and. +30mV (VOUT<1.5V) the output pin. The output voltage is set by laser trimming. Low Power Consumption 25 µA (TYP.) Voltages are selectable in 50mV steps within a range of Standby Current Less than 0.1 µA (TYP.) 0.9V to 5.0V. The XC6219 series is also fully compatible with low High Ripple Rejection 65dB (10kHz) ESR ceramic capacitors, reducing cost and improving output stability. Operating Temperature Range - 40OC to 85OC This high level of output stability is maintained even during frequent Low ESR Ceramic Compatible Ceramic Capacitor load fluctuations, due to the excellent transient response performance Ultra Small Packages SOT-25 (SOT-23-5) and high PSRR achieved across a broad range of frequencies. SOT-89 The CE function allows the output of regulator to be turned off, USP-6B resulting in greatly reduced power consumption. The XC6219 series is available in the SOT-25 (SOT-23-5), SOT-89 or USP-6B ‘chip-scale’ package. Measuring only 2.0mm x 1.8mm the USP-6B is perfect for applications where PCB area is critical.
