SOT23, Low-Cost, Low-Dropout, 3-Terminal Voltage References
_______________General Description
The MAX6125/MAX6141/MAX6145/MAX6150/MAX6160 low-dropout, micropower, three-terminal voltage references offer 2.5V, 4.096V, 4.5V, 5.0V, and adjustable (1.23V to 12.4V) output voltages, respectively. Low, 200mV dropout makes these devices ideal for 3V and 5V systems. Unlike two-terminal references that waste battery current and require an external resistor, the MAX61xx family's supply current is virtually independent of input voltage variations, which translates to longer battery life. Initial accuracy for these devices is 1%. The output temperature coefficient is typically 15ppm/C, and guaranteed to be less than 50ppm/C (except for the MAX6160). The MAX6125/MAX6141/MAX6145/ MAX6150 are available in 3-pin SOT23 and 8-pin SO packages. The MAX6160 is available in 4-pin SOT143 and 8-pin SO packages.

VADJ = 1.23V
which is also the nearest 0.1% resistor value. Choose R2 according to the following equation: R2 = R1 / (VOUT / VADJ - 1) For example, a 2.5V output requires R1 = (1.06 x 105) (2.5V / 1.23V) 215, which is the nearest standardvalue 0.1% resistor.
Figure 1. MAX6160 Adjustable Output Circuit
Input Bypassing
For the best line-transient performance, decouple the input with a 0.1F ceramic capacitor, as shown in the Typical Operating Circuit. Locate the capacitor as close to the device pin as possible. Where transient performance is less important, no capacitor is necessary.
_____________Applications Information
Setting the MAX6160 Output Voltage
Set the output voltage on the MAX6160 by connecting a resistor divider between OUT, ADJ, and GND (Figure 1). Choose R1 according to the following equation: R1 = (1.06 x 105) (VOUT / VADJ)(k) where VTH = 1.23V. The scaling factor (1.06 x 10 5) compensates for the MAX6160's change in ADJ input current over temperature. When R1 is chosen correctly, the change in voltage across R1 caused by the ADJ input current is properly cancelled. Choose R1 to within
Output Bypassing
The MAX6125/MAX6141/MAX6145/MAX6150/MAX6160 do not require an output capacitor. They are stable for capacitive loads from 0nF to 10nF. If your application requires an output charge reservoir (e.g., to decouple the reference from a DAC's input), then make sure that the total output capacitive load does not exceed 10nF for optimum settling-time performance.
