TLV2217-25PWR集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TLV2217-25PWR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TLV2217-25PWR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 TLV2217 family of low-dropout regulators offers

a variety of fixed-voltage options that offer a

maximum continuous input voltage of 16 V, making

them more versatile than CMOS regulators. Utilizing

a PNP pass element, these regulators are capable of

sourcing 500 mA of current, with a specified

maximum dropout of 500 mV (3.3-V and 2.5-V

options), making these regulators ideal for lowvoltage

applications. Additionally, the TLV2217

regulators offer very tight output accuracy of ±2%

across operating load and temperature ranges. Other

convenient features the regulators provide are

internal overcurrent limiting, thermal-overload

protection, and overvoltage protection. The TLV2217

family of regulators is available in fixed voltages of

1.8 V, 2.5 V, and 3.3 V.
