CAT6219  
500mA CMOS LDO Regulator  
FEATURES  
DESCRIPTION  
„ Guaranteed 500mA peak output current  
„ Low dropout voltage of 300mV typical at 500mA  
„ Stable with ceramic output capacitor  
„ External 10nF bypass capacitor for low noise  
„ Quick-start feature  
The CAT6219 is a 500mA CMOS low dropout  
regulator that provides fast response time during load  
current and line voltage changes.  
The quick-start feature allows the use of an external  
bypass capacitor to reduce the overall output noise  
without affecting the turn-on time of just 150μs.  
„ Under voltage lockout  
With zero shutdown current and low ground current of  
55μA typical, the CAT6219 is ideal for battery-  
operated devices with supply voltages from 2.3V to  
5.5V. An internal under voltage lockout circuit disables  
the output at supply voltages under 2.15V typical.  
„ No-load ground current of 55µA typical  
„ Full-load ground current of 85µA typical  
„ ±1.0% initial accuracy (VOUT ≥ 2.0V)  
„ ±2.0% accuracy over temperature (VOUT ≥ 2.0V)  
„ “Zero” current shutdown mode  
The CAT6219 offers 1% initial accuracy and low  
dropout voltage, 300mV typical at 500mA. Stable  
operation is provided with a small value ceramic  
capacitor, reducing required board space and compo-  
nent cost.  
„ Current limit and thermal protection  
„ 5-lead TSOT-23 and 6-pad TDFN packages  
APPLICATIONS  
Other features include current limit and thermal  
protection.  
„ Cellular phones  
„ Battery-powered devices  
„ Consumer Electronics  
The LDO is available in fixed and adjustable output in  
the low profile (1mm max height) 5-lead TSOT23 and in  
the 6-pad 2mm x 2mm TDFN packages.  
For Ordering Information details, see page 9.
