The NCV4279C is a 5.0 V precision micropower voltage regulator with an output current capability of 150 mA. The output voltage is accurate within ±2.0% with a maximum dropout voltage of 0.6 V at 150 mA. It has a low quiescent current of only 130 μA with a 100 μA load. This regulator is ideal for battery-operated microprocessor equipment. It features microprocessor control logic with an active RESET (with DELAY) and a FLAG monitor, which provides an early warning signal to the microprocessor of a potential impending RESET signal. The FLAG monitor allows the microprocessor to finish any signal processing before the RESET shuts it down. The active RESET circuit operates correctly at an output voltage as low as 1.0 V. The RESET function is activated during the power-up sequence or if the output voltage drops outside the regulation limits during normal operation. The reset threshold voltage can be decreased by connecting an external resistor divider to the RADJ lead. The regulator is protected against reverse battery, short circuit, and thermal overload conditions. It can withstand load dump transients, making it suitable for automotive environments. The device has also been optimized for EMC conditions.

The NCS2002 is an industry first sub−one volt operational amplifier that features a rail−to−rail common mode input voltage range, along with rail−to−rail output drive capability. This amplifier is guaranteed to be fully operational down to 0.9 V, providing an ideal solution for powering applications from a single cell Nickel Cadmium (NiCd) or Nickel Metal Hydride (NiMH) battery. Additional features include no output phase reversal with overdriven inputs, trimmed input offset voltage of 0.5 mV, extremely low input bias current of 40 pA, and a unity gain bandwidth of 1.1 MHz at 5.0 V. The NCS2002 also has an active high enable pin that allows external shutdown of the device. In the standby mode, the supply current is typically 1.9 μA at 1.0 V. Because of its small size and enable feature, this amplifier represents the ideal solution for small portable electronic applications.

The MC1455 is a highly stable timing circuit capable of producing accurate time delays or oscillation. It has additional terminals for triggering or resetting if desired. In the time delay mode, time is precisely controlled by one external resistor and capacitor. For astable operation as an oscillator, the free-running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor. The circuit may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200 mA or drive MTTL circuits.

The NCV1009 is a precision trimmed 2.5 V ±5.0 mV shunt regulator diode. The low dynamic impedance and wide operating current range enhances its versatility. The tight reference tolerance is achieved by on−chip trimming which minimizes voltage tolerance and temperature drift.
