Линейные регуляторы REG102NA-A/250

Стабилизатор с малым падением напряжения , регулируемый, 1.8В до 10В (Vin), 150мВ, 2.5В до 5.5В/250мА

The REG102NA-A/250 is a low-noise low-dropout Linear Regulator with low ground pin current. Its new DMOS topology provides significant improvement over previous designs, including low-dropout voltage (only 150mV typical at full load) and better transient performance. In addition, no output capacitor is required for stability, unlike conventional low-dropout regulator that is difficult to compensate and require expensive low ESR capacitors greater than 1µF. Typical ground pin current is only 600µA and drops to 10nA when not enabled. Unlike regulator with PNP pass devices, quiescent current remains relatively constant over load variations and under dropout conditions. The device has very low output noise, making it ideal for use in portable communications equipment. The device is well protected - internal circuitry provides a current limit that protects the load from damage, furthermore, thermal protection circuitry keeps the chip from being damaged by excessive temperature.
