AiT Semiconductor Inc. www.ait-ic.com A6306 REGULATOR 300mA HIGH PSRR, LINEAR REGULATOR REV1.0 - MAY 2012 RELEASED - - 1 - DESCRIPTION FEATURES A6306 series is a group of positive voltage output, low power consumption, low dropout voltage regulator. A6306 can provide output value in the range of 1.0V~4.4V every 0.1V step. It also can be customized on command. A6306 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module. A6306 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%. The A6306 is available in DFN4(1x1) packages. Low Power Consumption: 25uA (Typ.) Low output noise (47uV RMS) Standby Mode: 0.1uA Low dropout Voltage: 360mV@300mA (Typ.) High Ripple Rejection:74dB@100Hz (Typ.) Low Temperature Coefficient: ±100ppm/℃ Excellent Line regulation: 0.05%/V Build-in chip enable circuit Output Voltage Range: 1.0V~4.4V (customized on command every 0.1V step) Highly Accurate: ±2% Output Current Limit Available in DFN4 Packages APPLICATION Power source for cellular phones and various kind of PCSS Battery Powered equipment Power Management of MP3, PDA, DSC, Mouse, PS2 Games Reference Voltage Source Regulation after Switching Power
