250mA LOW POWER LOW DROPOUT MIDDLE CURRENT
DESCRIPTION
FEATURES
The A6250C series are precise, low power
consumption, high voltage; positive voltage
regulators manufactured using CMOS and laser
trimming technologies. The series provides large
currents with a significantly small dropout voltage.
The A6250C consists of a current limiter circuit, a
driver transistor, a precision reference voltage and
an error correction circuit. The series is compatible
with low ESR ceramic capacitors. The current
limiter's feedback circuit also operates as a short
protect for the output current limiter and the output
pin. Output voltage can be set internally by laser
trimming technologies. It is selectable in 100mV
increments within a range of 1.2V to 5.0V.
Output voltage range: 1.2V to 5.0V (selectable
in 100mV steps)
Highly optional accurate: ± 1% or ± 2%
Dropout voltage: 160mV @ 50mA (3.0V type)
Low power consumption: 2μA (TYP.)
Maximum output current: 250mA (VIN≥VOUT+1V)
Internal protector current limiter and short
protector
