GENERAL DESCRIPTION  
FEATURES  
The XC6219 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 XC6219 series  
is ideal for today’s cutting edge mobile phone.  
Maximum Output Current  
150mA (VOUT<1.75V)  
240mA (VOUT>1.8V)  
(300mA limit (TYP))  
200mV (IOUT=100mA)  
2.0V ~ 6.0V  
0.9V ~ 5.0V (50mV steps)  
+ 2% (VOUT>1.5V)  
+30mV (VOUT<1.5V)  
25µA (TYP.)  
Dropout Voltage  
Internally the XC6219 includes a reference voltage source, error  
amplifiers, driver transistors, current limiters and phase  
compensators. The XC6219’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 XC6219 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.  
Low ESR Ceramic Compatible  
Ultra Small Packages  
Ceramic Capacitor  
SOT-25 (SOT-23-5)  
SOT-89  
USP-6B  
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.
