ADP3339AKCZ-1.5-R7集成电路（IC）的线性+开关稳压器规格书PDF中文资料

ADP3339AKCZ-1.5-R7属于集成电路（IC）的线性+开关稳压器。由亚德诺半导体技术有限公司制造生产的ADP3339AKCZ-1.5-R7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。

GENERAL DESCRIPTION

The ADP3339 is a member of the ADP33xx family of precision, low dropout, anyCAP voltage regulators. The ADP3339 operates with an input voltage range of 2.8 V to 6 V and delivers a load current up to 1.5 A. The ADP3339 stands out from the conventional LDOs with a novel architecture and an enhanced process that enables it to offer performance advantages and higher output current than its competition. Its patented design requires only a 1.0 µF output capacitor for stability. This device is insensitive to output capacitor equivalent series resistance (ESR), and is stable with any good quality capacitor, including ceramic (MLCC) types for space-restricted applications.
