TLV76733DGNR集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TLV76733DGNR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TLV76733DGNR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 TLV767 is a wide input linear voltage regulator

supporting an input voltage range from 2.5 V to 16 V

and up to 1 A of load current. The output range is

from 0.8 V to 6.6 V or up to 14.6 V in the adjustable

version.

Additionally, the TLV767 has a 1% output

accuracy that can meet the needs of low voltage

microcontrollers (MCUs) and processors.

The TLV767 is designed to have a much lower

IQ than traditional wide-VIN regulators, thus making

the device well positioned to meet the needs of

increasingly stringent standby power requirements.

When disabled, the TLV767 draws only 1.5 μA of IQ.

The internal soft-start time and foldback current limit

reduce inrush current during start up, thus minimizing

input capacitance.

Wide bandwidth PSRR performance is greater than

70 dB at 1 kHz and 46 dB at 1 MHz, which helps

attenuate the switching frequency of an upstream

DC/DC converter and minimizes post regulator

filtering. To allow for more flexibility, the TLV767 has

both fixed and adjustable versions.

The TLV767 is available in a 6-pin, 2-mm × 2-mm

WSON (DRV), an 8-pin 3-mm x 3-mm HVSSOP

(DGN), and a 5-pin 2.9-mm x 1.6-mm SOT-23 (DBV)

package.
