GENERAL DESCRIPTION

The ADP3300 is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3300 stands out from conventional LDOs with a novel architecture and an enhanced process. Its patented design requires only a 0.47 µF output capacitor for stability. This device is stable with any capacitor, regardless of its ESR (Equivalent Series Resistance) value, including ceramic types (MLCC) for space restricted applications. The ADP3300 achieves exceptional accuracy of ±0.8 at room temperature and ±1.4 overall accuracy over temperature, line and load variations. The dropout voltage of the ADP3300 is only 80 mV (typical) at 50 mA.

The ADP3300 operates with a wide input voltage range from 3.0 V to 12 V and delivers a load current in excess of 50 mA.

It features an error flag that signals when the device is about to lose regulation or when the short circuit or thermal overload protection is activated. Other features include shutdown and optional noise reduction capabilities. The ADP330x anyCAP LDO family offers a wide range of output voltages and output current levels from 50 mA to 200 mA:

ADP3301 (100 mA)

ADP3302 (100 mA, Dual Output)

ADP3303 (200 mA)

ADP3300ART-2.7属于集成电路（IC） > 线性 + 开关稳压器。亚德诺半导体技术有限公司制造生产的ADP3300ART-2.7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。
