AiT Semiconductor Inc. www.ait-ic.com A6700 LOW DROPOUT VOL TAGE REGULATOR 700mA CMOS LOW NOISE WITH ENABLE PIN REV1.4 - MAY 2009 RELEASED, JUN 2017 UPDATED - - 1 - 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. 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. The CE function enables the output to be turned off, Resulting in greatly reduced power consumption. The A6700 is av ailable in SOT-25 and SOT 89-5 packages. 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 (VIN≧VOUT + 1V) Standby Current less than 0.1μA Internal protector : current limiter Available in SOT-25 and SOT89-5 Packages. APPLICATION CD-ROMs，CD-R/RW drive DVD drive HDD drive Cameras, Video cameras Portable AV equipment Battery powered equipment TYPICAL APPLICATION
