MAX6030 Overview

Precision, Low-Power, Low-Dropout, SOT23-3 Voltage References

19-4777; Rev 3; 4/01
Precision, Low-Power, Low-Dropout,
SOT23-3 Voltage References
General Description
The MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/
MAX6045/MAX6050 precision, low-dropout, micropower
voltage references are available in miniature SOT23-3
surface-mount packages. They feature a proprietary
curvature-correction circuit and laser-trimmed thin-film
resistors that result in a low temperature coefficient of
<15ppm/°C and initial accuracy of better than 0.2%.
These devices are specified over the extended temper-
ature range.
These series-mode voltage references draw only 27µA
of quiescent supply current and can sink or source up
to 500µA of load current. Unlike conventional shunt-
mode (two-terminal) references that waste supply cur-
rent and require an external resistor, devices in the
MAX6012 family offer a supply current that’s virtually
independent of supply voltage (with only a 0.8µA/V vari-
ation with supply voltage) and do not require an external
resistor. Additionally, these internally compensated
devices do not require an external compensation
capacitor and are stable with up to 2.2nF of load capac-
itance. Eliminating the external compensation capacitor
saves valuable board area in space-critical applications.
Their low dropout voltage and supply-independent,
ultra-low supply current make these devices ideal for
battery-operated, low-voltage systems.

How to choose MOS tube for low power motor
My motor has two operating voltages, 12V and 7V. The working current is 800mA at 7V. When starting, it needs to run at 12V for a while, and then switch to 7V. I want to use MOS tube to control the ope...
