DETAILED INFORMATION
A6120 is a series of low dropout voltage and low power consumption regulator. Its application circuitry
requires minimum number of external components. Both fixed voltage and adjustable voltage application
circuits need input and output capacitors to assure output voltage stability. Any desired output voltage from
fixed voltage to 18V can be achieved by assigning proper values to two external resistors in its application
circuitry (as shown in Fig.2, as R1, R2 are the two external resistors.).
A6120 uses trimming technique to assure the accuracy of output value within ±2%, at the same time,
temperature compensation is elaborately considered in this chip, which makes A6120’s temperature
coefficient within 100ppm/℃

TYPICAL APPLICATION
A6120 has fixed voltage and adjustable voltage application mode.
A 1μF ceramic capacitor connected between input and GND as bypass capacitor and a 1μF ceramic capacitor
between output and GND are recommended for all application.
Using a bypass capacitor (CADJ) between the adjust terminal and ground can improve ripple rejection. The
bypass capacitor prevents ripple from being amplified in case the output voltage is increased. The impedance
of CADJ should be less than the resistance of R1 to prevent ripple from being amplified at any frequency. As R1
is normally in the range of 1kΩ~10kΩ, the value of CADJ should satisfy the following condition:
1/(2π* FrequencyRipple *CADJ)<R1
A 0.1μF ceramic capacitor is recommended.
Fig 2. Typical Application of A6120
EXPLANATION
The output voltage of adjustable application satisfies this followed equation:
VOUT=VREF× (1+R2/R1)+IADJ×R2.
The second term IADJ×R2 can be ignored since the adjustable pin current IADJ (~ 2μA) is much less than the
current through R1 (~1mA).
The value of R1 is preferred in the range of 1kΩ～10kΩ and the value of VREF is the output voltage of typical
fixed voltage application circuit.
