A6250
LOW DROPOUT VOLTAGE REGULATOR
250mA CMOS LOW QUIESCENT CURRENT
DESCRIPTION
The A6250 is a series of low dropout regulators to
provide fixed positive output from 1.2V~6.0V
(0.1V increasing).
The A6250 offers low power consumption, low
quiescent current (Iq=3.0uA) to have longer
battery life.
The A6250 includes high accuracy voltage
reference, error amplifier, current limit circuit and
output driver module.
The A6250 has well load transient response and
good temperature characteristic, which can
assure the stability of chip and power system.
The A6250 is available in SOT-23 and SOT-89
package.
