NTE1900 Integrated Circuit 3-Terminal Adjustable Positive Voltage Regulator
Description: NTE1900 adjustable 3-terminal positive voltage regulator TO92 type package capable supplying excess 100mA over 1.2V output range. This device exceptionally easy both line load regulation better than standard fixed regulators. addition higher performance than fixed regulators, NTE1900 offers full overload protection available only IC's. Included chip current limit, thermal overload protection, safe area protection. overload protection circuitry remains fully functional even adjustment terminal disconnected. Normally, capacitors needed unless device situated from input filter capacitors which case input bypass needed. optional output capacitor added improve transient response. adjustment terminal bypassed achieve very high ripple rejection ratios which difficult achieve with standard 3-terminal regulators. Besides replacing fixed regulators, NTE1900 useful wide variety other applications. Since regulator "floating" sees only input-to-output differential voltage, supplies several hundred volts regulated long maximum input output differential exceeded. Also, makes especially simple adjustable switching regulator, programmable output regulator, connecting fixed resistor between adjustment output, NTE1900 used precision current regulator. Supplies with electronic shutdown achieved clamping adjustment terminal which programs output 1.2V where most loads draw little current.
