TPS71501MDCKREP集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TPS71501MDCKREP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TPS71501MDCKREP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 TPS71501 low-dropout (LDO) voltage regulators

offer the benefits of high input voltage, low dropout

voltage, low-power operation, and miniaturized

packaging. The device, which operates over an input

range of 2.5 V to 24 V, is stable with any capacitor

(≥0.47 mF). The low dropout voltage and low

quiescent current allow operation at extremely low

power levels. Therefore, the devices are ideal for

powering battery-management ICs. Specifically, because the devices are enabled as soon as the

applied voltage reaches the minimum input voltage,

the output is quickly available to power continuously

operating battery-charging ICs.

The usual PNP pass transistor has been replaced by

a PMOS pass element. Because the PMOS pass

element behaves as a low-value resistor, the low

dropout voltage, typically 415 mV at 50 mA of load

current, is directly proportional to the load current. The low quiescent current (3.2 mA typically) is stable

over the entire range of output load current (0 mA to

50 mA).
