A6700

LOW DROPOUT VOLTAGE REGULATOR

700mA CMOS LOW NOISE WITH ENABLE PIN

AiT Semiconductor Inc.

DESCRIPTION

FEATURES

The A6700 series are highly precise, low noise,

positive voltage LDO regulators manufactured using

CMOS processes. The A6700 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. Output voltage is selectable in 100mV

increments within a range of 1.0V ~ 5.0V.



Output Voltage Range 1.0V to 5.0V (selectable

in 100mV steps)



Highly Accurate ±2%

Dropout Voltage 50mV @ 100mA (3.0V type)

High Ripple Rejection 60dB (1 kHz)

Low Power Consumption 30μA (TYP.)

Maximum Output Current: more than 700mA

(V_IN≧V_OUT+ 1V)



Standby Current less than 0.1μA

Internal protector : current limiter

Available in SOT-25 and SOT89-5 Packages.

The A6700 series is also compatible with low ESR

ceramic capacitors which give added output stability.

This stability can be maintained even during load

fluctuations due to the excellent transient response of

the A6700 series.

APPLICATION



CD-ROMs，CD-R/RW drive

DVD drive

HDD drive

The CE function enables the output to be turned off,

Resulting in greatly reduced power consumption.

Cameras, Video cameras

Portable AV equipment

Battery powered equipment

The A6700 is available in SOT-25 and SOT89-5

packages.
