BD733L5FP-C集成电路（IC）的线性+开关稳压器规格书PDF中文资料

BD733L5FP-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BD733L5FP-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 BD7xxL5FP-C are low quiescent regulators

featuring 50V absolute maximum voltage, and output

voltage accuracy of ±2, 500mA output current and 6μA

Typ.) current consumption. There 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.
