TLV70233QDBVRQ1集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TLV70233QDBVRQ1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TLV70233QDBVRQ1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 TLV702-Q1 series of low-dropout (LDO) linear

regulators are low quiescent current devices with

excellent line and load transient performance. These

LDOs are designed for power-sensitive applications.

A precision bandgap and an error amplifier provide

overall 2% accuracy. Low output noise, very high

power-supply rejection ratio (PSRR), and low-dropout

voltage make this series of devices ideal for a wide

selection of battery-operated equipment. All device

versions have thermal shutdown and current limit

protections 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. The devices regulate to specified accuracy

with no output load.

The TLV702-Q1 series of LDO linear regulators is

available in SOT and WSON packages.
