NTE923 General Description

The NTE923 and NTE923D are voltage regulators designed primarily for series regulator applications.

By themselves, these devices will supply output currents up to 150mA; but, external transistors can be added to provide any desired load current. The circuits feature extremely low standby current drain, and provision is made for either linear or foldback current limiting.

These devices are also useful in a wide range of other applications such as shunt regulators, current regulators, and temperature controllers.

NTE937M General Description

The NTE937M is a monolithic JFET input operational amplifier in an 8–Lead DIP type package incorporating well–matched, high voltage JFET’s on the same chip with standard bi–polar transistors. This amplifier features low input bias and offset currents, low offset voltage and offset voltage drift, coupled with offset adjust which does not degrade drift or common–mode rejection. It is also designed for high slew rate, wide bandwidth, extremely fast settling time, low voltage and current noise and a low 1/f noise corner.

Note 1. The maximum power dissipation for this device must be derated at elevated temperatures and is dictated by T_Jmax, R_thJC, and the ambient temperature, T_A. The maximum available power dissipation at any temperature is P_d = (T_Jmax – T_A)/R_thJC or the +25°C Pdmax, whichever is less.
Note 2. Unless otherwise specified, the absolute maximum negative input voltage is equal to the negative power supply voltage.
