A6312
LOW DROPOUT CMOS VOLTAGE REGULATOR
300mA WIDE INPUT VOLTAGE, LOW CONSUMPTION
DESCRIPTION
FEATURES
The A6312 series of fixed output low dropout linear regulators
are designed for portable battery powered applications which
require low noise operation, fast enable response time, and
low dropout. The device achieves its low noise performance
without the need of an external noise bypass capacitor.
The A6312 can provide output value in the range of 2.5V~5V
every 0.1V increasing. The A6312 also can be customized on
request.
The A6312 includes high accuracy voltage reference, error
amplifier, current limit circuit and output driver module with
discharge capability, The A6312 series have excellent load
and line transient response and good temperature
characteristics, which can assure the stability of chip and
power system. And it uses trimming technique to guarantee
output voltage accuracy within ±2%.
Low Power Consumption: 8uA (Typ.)at 5V
Low Output Noise (44uVRMS)
Low Dropout Voltage:
270mV@150mA(Typ.)load
High Ripple Rejection: 60dB@10KHz(Typ.)
Low Temperature Coefficient:±100ppm/oC
Excellent Line Regulation: 0.05%/V
Highly Accurate: ±2%
Available in SOT-23, SOT-25, SOT-89-3
package.
