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

（V_IN≧V_OUT+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!
