LD29150中文资料1.5 A极低压降稳压器数据手册ST规格书

描述 Description

The LD29150 is a high current, high accuracy, low-dropout voltage regulator series. These regulators feature 400 mV dropout voltage and very low ground current. Designed for high current loads, these devices are also used in lower current, extremely low dropout-critical systems, where their tiny dropout voltage and ground current values are important attributes. Typical applications are in power supply switching post regulation, series power supply for monitors, series power supply for VCRs and TVs, computer systems and battery powered systems.

特性 Features

• Very low dropout voltage (typ. 0.4 at 1.5 A)
• Guaranteed output current up to 1.5 A
• Fixed and adjustable output voltage (± 1% at 25 °C)
• Internal current and thermal limit
• Logic controlled electronic shutdown available in PPAK

简介

LD29150属于集成电路（IC）的线性+开关稳压器。由制造生产的LD29150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。
