UA723CDR集成电路（IC）的线性+开关稳压器规格书PDF中文资料

UA723CDR属于集成电路（IC）的线性+开关稳压器。由德州仪器制造生产的UA723CDR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。

description

The mA723 is a precision integrated-circuit

voltage regulator, featuring high ripple rejection,

excellent input and load regulation, excellent temperature stability, and low standby current. The circuit consists

of a temperature-compensated reference-voltage amplifier, an error amplifier, a 150-mA output transistor, and

an adjustable-output current limiter.

The mA723 is designed for use in positive or negative power supplies as a series, shunt, switching, or floating

regulator. For output currents exceeding 150 mA, additional pass elements can be connected as shown in

Figures 4 and 5.

The mA723C is characterized for operation from 0°C to 70°C.
