LM2936QDT-3.0/NOPB集成电路（IC）的线性+开关稳压器规格书PDF中文资料

LM2936QDT-3.0/NOPB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LM2936QDT-3.0/NOPB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 LM2936Q ultralow quiescent-current regulator

features low dropout voltage and low current in the

standby mode. With less than 15-μA quiescent

current at a 100-μA load, the LM2936Q is ideally

suited for automotive and other battery-operated

systems. The LM2936Q retains all of the features that

are common to low-dropout regulators including a low

dropout PNP pass device, short-circuit protection,

reverse battery protection, and thermal shutdown.

The LM2936Q has a 40-V maximum operating

voltage limit, a −40°C to +125°C operating

temperature range, and ±3% output voltage tolerance

over the entire output current, input voltage, and

temperature range. The LM2936Q is available in

8-pin SOIC and VSSOP packages, a 4-pin SOT–223

package, as well as a 3-pin TO-252 surface mount

package.
