AiT Semiconductor Inc. www.ait-ic.com A6110A LOW DROPOUT VOL TAGE REGULATOR 1A CMOS LOW NOISE WITH ENABLE PIN REV1.2 - JUN 2014 RELEASED, DEC 2019 UPDATED - - 1 - DESCRIPTION FEATURES The A6110A series are highly precise, low nois e, positive voltage LDO regulators manufactured using CMOS processes. The A6110A 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 1.5V ~ 5.0V. The A6110A series is also compatible with low ESR ceramic capacitors which give added o utput stability. This stability can be maintained even during load fluctuations due to the excellent transient response of the A6110A series. The CE function enables the output to be turned off, Resulting in greatly reduced power consumption. The A6110A is available in SOT-25 a nd SOT 89-5 packages. Output Voltage Range 1.5V 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 1000mA (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 ORDER INFORMATION Package Type Part Number SOT-25 SPQ: 3,000pcs/Reel E5 A6110AE5R-XX A6110AE5VR-XX SOT89-5 SPQ: 1,000pcs/Reel K5 A6110AK5R-XX A6110AK5VR-XX Note XX: Output Voltage, 18=1.8V, 33=3.3V R: Tape & Reel V: Halogen free Package AiT provides all RoHS products
