LP2983IM5X-1.0/NOPB集成电路（IC）的线性+开关稳压器规格书PDF中文资料

LP2983IM5X-1.0/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LP2983IM5X-1.0/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 LP2983 is a 150-mA, fixed-output voltage

regulator designed to provide tight voltage regulation

in applications with output voltages ≤ 1.2 V.

Using an optimized vertically integrated PNP (VIP)

process, the LP2983 delivers unequaled performance

in all critical specifications:

• Ground pin current: Typically 825 μA at a 150-mA

load, and 75 μA at a 1-mA load.

• Enhanced stability: The LP2983 is stable with

output capacitor ESR down to zero, which allows

the use of ceramic capacitors on the output.

• Precision output: 1% tolerance output voltages

available (A grade).

• Smallest possible size: SOT-23 package uses

absolute minimum board space.
