Description
The 3 17 are adjustable 3 - terminal positive -voltage regulators capable of supplying 1.5A over a differential voltage range of 3Vto 40V. They are exceptionally easy to use and require only two external resistors to set the output voltage.
Both input and output regulation are better than standard fixed regulators.In addition to higher performance than fixed regulators, these regulators offer full overload protection available only in integrated circuits. Included on the chip are current limit, thermal overload protection, and safe-area protection. All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected. Normally, no capacitors are needed unless the device is situated far from the input filter capacitors in which case an input bypass is needed. An optional output capacitor can be added to improve transient response.The primary applications of each of these regulators is that of a programmable output regulator, but by connecting a fixed resistor between adjustment terminal and the output terminal, each device can be used as a
precision current regulator. Even though the regulator is floating and sees only the input-to-output differential voltage, use of these devices to regulate output voltages that would cause the maximum-rated differential voltage to be exceeded if the output became shorted to ground is not recommended.

Features
*Output Voltage Range Adjustable from 1.2 V to 37 V
*Output Current Capability of 1.5 A Max
*Input Regulation Typically 0.01 % Per Input - Volt Change
*Output Regulation Typically 0.1 %
*Peak Output Current Constant Over Temperature Range of Regulator
*Popular 3-Lead TO-220 Package
*Ripple Rejection Typically 80 dB

The MAX809 and MAX810 are cost–effective system supervisor circuits designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. No external components are required.
The reset output is driven active within 20 msec of VCC falling through the reset voltage threshold. Reset is maintained active for a minimum of 140msec after VCC rises above the reset threshold. The MAX810 has an active–high RESET output while the MAX809 has
an active–low RESET output. The output of the MAX809 is guaranteed valid down to VCC = 1V. Both devices are available in a SOT–23 package.
The MAX809/810 are optimized to reject fast transient glitches on the VCC line. Low supply current of 17mA (VCC = 3.3V) makes these devices suitable for battery powered applications.
