A6318A  
LOW DROPOUT VOLTAGE REGULATOR  
AiT Semiconductor Inc.  
www.ait-ic.com  
300mA LOW DROPOUT PROGRAMMABLE OUTPUT  
DESCRIPTION  
FEATURES  
The A6318A series are highly precise, low noise,  
positive voltage LDO regulators manufactured using  
CMOS processes. The series achieves high ripple  
rejection and low dropout and consists of a standard  
voltage source, an error correction, current limiter  
and a phase compensation circuit plus a driver  
transistor. External output feedback, customers can  
easily get the required voltage. In order to make the  
load current does not exceed the current capacity of  
the output transistor, built-in over-current protection,  
over temperature protection and short circuit  
protection.  
programmable output: Minimum can go to 0.8V  
Highly Accurate: ± 1.5%  
Dropout Voltage: 300mV @ 100mA (3.0V type)  
High Ripple Rejection: 50dB (10kHz)  
Low Power Consumption: 30μA (TYP.)  
Maximum Output Current : 300mA  
VINVOUT+1V)  
Standby Current : less than 0.1μA  
Internal protector: current limiter ,short protector  
and over temperature protection  
Instructions with POWER GOOD  
Available in SOT-25 Package  
A6318A may have the POWER GOOD indicator.  
When the FB voltage reaches 0.75V, PG output is  
high. When the FB drops below 0.7V, PG output is  
low. The internal op amp with advanced structure, the  
output capacitor can be omitted!  
APPLICATION  
Mobile phones  
Cordless phones  
Cameras, Video cameras  
Portable games  
The A6318A is available in SOT-25 package.  
Portable AV equipment
