DESCRIPTION
FEATURES
The A6110A series are highly precise, low noise,
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.
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.
The A6110A 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 A6110A 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 A6110A is available in SOT-25 and SOT-89-5
packages.
