BD733L2EFJ-C集成电路（IC）的线性+开关稳压器规格书PDF中文资料

BD733L2EFJ-C属于集成电路（IC）的线性+开关稳压器。由罗姆半导体集团制造生产的BD733L2EFJ-C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 BD7xxL2EFJ-C, BD7xxU2EFJ-C,

BD7xxL2FP-C, BD7xxL2FP3-C are low quiescent

regulators featuring 50V absolute maximum voltage,

and output voltage accuracy of ±2, 200mA output

current and 6μA (Typ) current consumption. These

regulators are therefore ideal for applications

requiring a direct connection to the battery and a

low current consumption. Ceramic capacitors can

be used for compensation of the output capacitor

phase. Furthermore, these ICs also feature

overcurrent protection to protect the device from

damage caused by short-circuiting and an

integrated thermal shutdown to protect the device

from overheating at overload conditions.
