TPS7A8001DRBT

Стабилизатор с малым падением напряжения, регулируемый, 2.2В до 6.5В (Vin), 500мВ, 800мВ до 6В/1А.

The TPS7A8001DRBT is a low-dropout Linear Regulator (LDO) offering very high power-supply ripple rejection (PSRR) at the output. This LDO uses an advanced BiCMOS process and a PMOSFET pass device to achieve very low noise, excellent transient response and excellent PSRR performance. The device is stable with a 4.7µF ceramic output capacitor and uses a precision voltage reference and feedback loop to achieve a worst-case accuracy of 3% over all load, line, process and temperature variations. A noise-reduction capacitor (C(NR)) at the NR pin and a bypass capacitor (C(BYPASS)) decrease noise generated by the band-gap reference to improve PSRR, while a quick-start circuit fast-charges the noise-reduction capacitor.
