TLV75201PDSQT集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TLV75201PDSQT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TLV75201PDSQT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 TLV752 is a dual, adjustable, 1-A low-dropout

(LDO) regulator. This device is available in a small,

10-pin, 2-mm × 2-mm WSON package and consumes

25-μA quiescent current while providing fast line and

load transient response. The TLV752 features a low

dropout of 225 mV that can help improve the overall

power efficiency.

The TLV752 wide input-and-output voltage ranges,

when combined with its output current capability in a

small printed circuit board (PCB) footprint help

support a wide variety of applications from sensor

supplies, to auxiliary rails, and modern

microcontrollers with lower core voltages.

The TLV752 is stable with small ceramic output

capacitors, allowing for a small overall solution size.

A precision band-gap and error amplifier provides

high accuracy of 1.5% (max) over temperature. This

device includes integrated thermal shutdown, current

limit, active output-discharge, and undervoltage

lockout (UVLO) features. The TLV752 has an internal

fold-back current-limit to reduce thermal dissipation

during short-circuit events.
