Integrated Circuit

Negative Adjustable Voltage Regulator,

–1.2V to –37V, 100mA

Description:

The NTE1901 is an adjustable 3–terminal negative voltage regulator in a TO92 type package capable

of supplying 100mA over a –12,V to –37V output range. It 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 NTE1901 offers full overload protection.

Included on the chip are current limit, thermal overload protection and safe area protection. All over-

load protection circuitry remains fully functional even if the adjustment terminal is disconnected.

Normally, no capacitors are needed unless the device is situated more than 6 inches from the input

filter capacitor in which case an input bypass is needed. An optional output capacitor can be added

to improve transient 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 NTE1901 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 sev-

eral hundred volts can be regulated as long as the maximum input–to–output differential is not ex-

ceeded.

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 NTE1901 can be used as

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

adjustment terminal to ground 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 Standard 3–Lead Transistor Package

D 80db Ripple Rejection

D Output is Short Circuit Protected
