Integrated Circuit

3–Terminal Adjustable Positive

Voltage Regulator

Description:

The NTE1900 is an adjustable 3–terminal positive voltage regulator in a TO92 type package capable

of supplying in excess of 100mA over a 1.2V to 37V output range. This device is exceptionally easy

to use and both line and load regulation are better than standard fixed regulators.

In addition to higher performance than fixed regulators, the NTE1900 offers full overload protection

available only in IC’s. 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 termi-

nal 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 tran-

sient response. The adjustment terminal can be bypassed to achieve very high ripple rejection ratios

which are difficult to achieve with standard 3–terminal regulators.

Besides replacing fixed regulators, the NTE1900 is useful in a wide variety of other applications. Since

the regulator is “floating” and sees only the input–to–output differential voltage, supplies of several

hundred volts can be regulated as long as the maximum input to output differential is not exceeded.

Also, it makes an especially simple adjustable switching regulator, a programmable output regulator,

or by connecting a fixed resistor between the adjustment and output, the NTE1900 can be used as

a precision current regulator. Supplies with electronic shutdown can be achieved by clamping the

adjustment terminal to GND which programs the output to 1.2V where most loads draw little current.

Features:

D Adjustable Output Down to 1.2V

D Guaranteed 100mA Output Current

D Line Regulation Typically 0.01%/V

D Load Regulation Typically 0.1%

D Current Limit Constant with Temperature

D Eliminates the Need to Stock Many Voltages

D 80dB Ripple Rejection
