LDCL015数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The LDCL015 provides 150 mA of maximum current from an input voltage ranging from 1.8 V to 5.5 V, with a typical dropout voltage of 50 mV. It is stable with no input or output capacitor. Low quiescent current, low noise and capless operation make it suitable for low power battery- powered applications and allows the reduction of board size. Typical power supply rejection ratio is 52 dB at low frequencies, and starts to roll off at 10 kHz. The Enable logic control function puts the LDCL015 in shutdown mode, reducing the total current consumption to less than 1 μA. The device also includes short-circuit constant current limit and thermal protection. Typical applications are mobile phones, personal digital assistants and similar battery-powered systems.

简介

LDCL015属于集成电路（IC）的线性+开关稳压器。由制造生产的LDCL015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。
