TPS71701DCKR .

Регулируемый стабилизатор с малым падением напряжения, 2.5В - 6.5В, 170мВ, 900мВ - 4.8В/150мА.

The TPS71701DCKR is a low-dropout (LDO) low-power Linear Regulator offers very high power-supply rejection (PSRR) while maintaining very low 45µA ground current in an ultra-small. It uses an advanced BiCMOS process and a PMOS pass device to achieve fast start-up, very low noise, excellent transient response and excellent PSRR performance. The device is stable with a 1µF 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. It combines the high performance required by many RF and precision analog applications with ultra-low current consumption. High PSRR is provided by a high-gain, high-bandwidth error loop with good supply rejection with very low headroom. Fixed voltage versions provide a noise reduction pin to bypass noise generated by the band-gap reference and to improve PSRR. A quick-start circuit fast-charges this capacitor at start-up.
