LM2936Z-5.0/LFT3集成电路（IC）的线性+开关稳压器规格书PDF中文资料

LM2936Z-5.0/LFT3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LM2936Z-5.0/LFT3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 LM2936 ultra-low 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 LM2936 is ideally suited

for automotive and other battery operated systems.

The LM2936 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 LM2936 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 LM2936 is available in a TO-92 through-hole

package, as well as SOIC-8, VSSOP, SOT–223, and

TO-252 surface mount packages.
