TLV75901PDRVR集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TLV75901PDRVR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TLV75901PDRVR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 TLV759P is an adjustable 1-A low-dropout (LDO)

regulator. This device is available in a small, 6-pin,

2-mm × 2-mm WSON package and consumes very

low quiescent current and provides fast line and load

transient performance. The TLV759P features an

ultra-low dropout of 225 mV at 1 A that can help

improve the power efficiency of the system.

The TLV759P is optimized for a wide variety of

applications by supporting an input voltage range

from 1.5 V to 6.0 V and an externally adjustable

output range of 0.55 V to 5.5 V. The low output

voltage enables this LDO to power the modern

microcontrollers with lower core voltages.

Additionally, the TLV759P has a low IQ with enable

functionality to minimize standby power. This device

features an internal soft-start to lower the inrush

current, which provides a controlled voltage to the

load and minimizes the input voltage drop during start

up.

The TLV759P is stable with small ceramic output

capacitors, allowing for a small overall solution size.

A precision band-gap and error amplifier provides a

high accuracy of 0.7% max at 25ºC and 1% max over

temperature (85ºC). This device includes integrated

thermal shutdown, current limit, and undervoltage

lockout (UVLO) features. The TLV759P has an

internal foldback current limit that helps reduce the

thermal dissipation during short-circuit events.
