AZ1117R-ADJTRE1集成电路（IC）的线性+开关稳压器规格书PDF中文资料

AZ1117R-ADJTRE1属于集成电路（IC）的线性+开关稳压器。由美台半导体制造生产的AZ1117R-ADJTRE1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。

描述 Description

The AZ1117 is a series of low dropout three-terminal regulators with a

dropout of 1.15V at 1A output current.

The AZ1117 series provides current limiting and thermal shutdown.

Its circuit includes a trimmed bandgap reference to assure output

voltage accuracy to be within 1% for 1.5V, 1.8V, 2.5V, 2.85V, 3.3V,

5.0V and adjustable versions or 2% for 1.2V version. Current limit is

trimmed to ensure specified output current and controlled short-circuit

current. On-chip thermal shutdown provides protection against any

combination of overload and ambient temperature that would create

excessive junction temperature.

The AZ1117 has an adjustable version, which can provide the output

voltage from 1.25V to 12V with only 2 external resistors.

The AZ1117 series is available in the industry standard SOT223,

SOT89, TO220-3, TO252-2 (3), TO252-2 (4), TO252-2 (5) and TO263

power packages.
