LC1463 DESCRIPTION 300mA High PSRR, Fast Response Linear Regulator FEATURES LC1463 series is a group of positive voltage output, low power consumption, low dropout voltage regulator. LC1463 can provide output value in the range of 1.0V~4.5V every 0.1V step. It also can be customized on command. LC1463 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module with discharge capability. LC1463 has 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%. LC1463 is available in SOT-23-5, SC-70-5 and SOT23-3 packages which is lead free. • • • • • • • • • • • Low Power Consumption: 25uA（Typ.） Low output noise (47uVRMS) Standby Mode: 0.1uA Low dropout Voltage: 0.16V@300mA (Typ.)
