3 Description
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.
TPS7A2042PDQNR属于集成电路(IC) > 线性 + 开关稳压器。美国德州仪器公司制造生产的TPS7A2042PDQNR稳压器 - 线性线性稳压器用于提供稳定的输出电压,无论负载电流、输入电压或环境因素如何变化,这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压,而且要超出某个最小量,并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言,虽然这种稳压器的效率低于开关模式的稳压器,但它们通常更适合对噪声高度敏感的应用。
