The NE5230 is a very low voltage operational amplifier that can perform with a voltage supply as low as 1.8 V or as high as 15 V. In addition, split or single supplies can be used, and the output will swing to ground when applying the latter. There is a bias adjusting pin which controls the supply current required by the device and thereby controls its power consumption. If the part is operated at +/-0.9 V supply voltages, the current required is only 110 uA when the current control pin is left open. Even with this low power consumption, the device obtains a typical unity gain bandwidth of 250 kHz. When the bias adjusting pin is connected to the negative supply, the unity gain bandwidth is typically 600 kHz while the supply current is increased to 600 uA. In this mode, the part will supply full power output beyond the audio range.The NE5230 also has a unique input stage that allows the common−mode input range to go above the positive and below the negative supply voltages by 250 mV. This provides for the largest possible input voltages for low voltage applications. The part is also internally−compensated to reduce external component count.The NE5230 has a low input bias current of typically +/-40 nA, and a large open−loop gain of 125 dB. These two specifications are beneficial when using the device in transducer applications. The large open−loop gain gives very accurate signal processing because of the large "excess" loop gain in a closed−loop system.The output stage is a class AB type that can swing to within 100 mV of the supply voltages for the largest dynamic range that is needed in many applications. The NE5230 is ideal for portable audio equipment and remote transducers because of its low power consumption, unity gain bandwidth, and 30 nV//Hz noise specification.

This low dropout (LDO) linear voltage regulator provides up to 500 mA over a user-adjustable output range of 1.25 V to 5.0 V, or at a fixed output voltage of 1.5 V, 3.3 V or 5.0 V, with typical output voltage accuracy better than 3%. An internal PNP pass transistor permits low dropout voltage and operation at full load current at the minimum input voltage. NCV versions are qualified for demanding automotive applications that require extended temperature operation and site and change control. NCP5500 and NCV5500 versions include an Enable/Shutdown function and are available in a DPAK 5 and SOIC 8 packages. NCP5501 and NCV5501 versions are available in DPAK 3 for applications that do not require logical on/off control. This regulator family is ideal for applications that require a broad input voltage range, and low dropout performance up to 500 mA load using low cost ceramic capacitors. Integral protection features include short circuit current and thermal shutdown.

The NCV5504 Low Dropout (LDO) Linear Voltage Regulator is a dual output low dropout linear voltage regulator with +/-2.0% accuracy over the operating temperature range. It features a fixed output voltage of 3.3 V (contact the factory for other fixed output voltage options) and an adjustable output that ranges from 1.25 V to 5.0 V. It is available in a 5 pin DPAK Pb-free package.The NCV5504 provides low noise operation without a bypass capacitor for the fixed output. This device has ripple rejection of 75 dB and a dropout of 250 mV @ 250 mA and is suitable for post-regulation and power sensitive battery operated applications.

The NCP551 series of fixed output low dropout (LDO) linear voltage regulators are designed for applications which require low quiescent current. The NCP551 series features an ultra-low quiescent current of 4.0 µA. Each device contains a voltage reference unit, an error amplifier, a PMOS power transistor, resistors for setting output voltage, current limit, and temperature limit protection circuits.The NCP551 has been designed to be used with low cost ceramic capacitors and requires a minimum output capacitor of 0.1 µF. The device is housed in the micro miniature TSOP-5 surface mount package. Standard voltage versions are 1.4, 1.5, 1.8, 2.5, 2.7, 2.8, 3.0, 3.3, and 5.0 V. Other voltages are available in 100 mV steps.

The NCP565/NCV565 low dropout linear regulator provides 1.5 A in either fixed voltage options or in an adjustable voltage version from 7.7 V down to 0.9 V. The fast loop response and low dropout voltage make this regulator ideal for applications where low voltage and good load transient response are important. Device protection includes a current limit, short circuit protection, and thermal shutdown. The NCP565 is packaged in D2PAK, DFN6 or SOT-223.

The NCx5652 is a dual power operational amplifier with a versatile output stage configuration that allows conventional op-amp biasing or user tuning of efficiency, isolation, or current monitoring. Integrated flyback diodes protect the amplifiers during inductive load transients. Operating at supply voltages as low as 3.3 V, the NCx5652 is capable of delivering 500 mA of current while maintaining an excellent output swing. The integrated thermal shutdown circuit protects the NCx5652 from excessive power dissipation. A thermal warning flag is provided for external monitoring of the device, providing a flexible interface to a system’s microcontroller. This open-collector thermal flag output doubles as a -DISABLE input that can be used to tri-state both amplifier outputs under user control. The 12-pin UDFN 3x3 mm package provides thermal robustness while achieving space savings on high density PCBs.
