TLV70725DQNR集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TLV70725DQNR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TLV70725DQNR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 TLV707 series (TLV707 and TLV707P) of lowdropout

linear regulators (LDOs) are low quiescent

current devices with excellent line and load transient

performance for power-sensitive applications. These

devices provide a typical accuracy of 0.5. All

versions have thermal shutdown and overcurrent

protection for safety.

Furthermore, these devices are stable with an

effective output capacitance of only 0.1 μF. This

feature enables the use of cost-effective capacitors

that have higher bias voltages and temperature

derating. These devices also regulate to the specified

accuracy with no output load.

The TLV707P also provides an active pulldown circuit

to quickly discharge the outputs.

The TLV707 series of LDOs are available in a 1-mm

× 1-mm DQN (X2SON) package that makes them

desirable for handheld applications.
