TPS7A2028PDBVR 原装 低压差稳压器 的描述：
The TPS7A20 is an ultra-small, low-dropout (LDO) linear regulator that can source 300 mA of output current. The TPS7A20 is designed to provide low noise, high PSRR, and excellent load and line transient performance that can meet the requirements of RF and other sensitive analog circuits.
Using innovative design techniques, the TPS7A20 offers an ultra-low noise performance without the addition of a noise bypass capacitor. The TPS7A20 also provides the advantage of low quiescent current, which can be ideal for battery-powered applications.
With an input voltage range of 1.6 V to 6.0 V and an output range of 0.8 V to 5.5 V, the TPS7A20 can be used for a wide variety of applications. The device uses a precision reference circuit to provide a maximum accuracy of 1.5% over load, line, and temperature variations. The TPS7A20 features an internal soft-start to lower the inrush current, thus minimizing the input voltage drop during start up.
The device is stable with small ceramic capacitors, allowing for a small overall solution size. The TPS7A20 has a smart enable input circuit with an internally controlled pulldown resistor that keeps the LDO disabled even when the EN pin is left floating and helps eliminate the external components used to pulldown the EN pin.
