TPS7101QDG4

Стабилизатор с малым падением напряжения, регулируемый, 2.5В до 10В (Vin), 32мВ, 1.2В до 9.75В/0.5А.

The TPS7101QDG4 is a micro-power low-dropout Voltage Regulator with an order of magnitude reduction in dropout voltage and quiescent current over conventional LDO performance is achieved by replacing the typical PNP pass transistor with a PMOS device. Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and remains independent of output loading. These two key specifications yield a significant improvement in operating life for battery-powered systems. The LDO also features a sleep mode, applying a TTL high signal to EN shuts down the regulator, reducing the quiescent current to 0.5µA maximum at TJ = 25°C. Voltage - power good (PG) reports low output voltage and can be used to implement a power-ON reset or a low-battery indicator.
