TPS73601QDBVRQ1集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TPS73601QDBVRQ1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TPS73601QDBVRQ1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。

3 Description

The TPS736-Q1 low-dropout (LDO) linear voltage

regulator uses an NMOS topology consisting of

an NMOS pass transistor in a voltage-follower

configuration. This topology is stable using output

capacitors with low ESR, and even allows operation

without a capacitor. This topology also provides high

reverse blockage (low reverse current) and ground pin

current that is nearly constant over all values of output

current.

The TPS736-Q1 uses an advanced BiCMOS process

to yield high precision while delivering very low

dropout voltages and low ground pin current. Current

consumption, when not enabled, is under 1μA and

ideal for portable applications. The extremely low

output noise (30μVRMS with 0.1μF CNR) is ideal for

powering VCOs. This device is protected by thermal

shutdown and foldback current limit.
