Description

The LD39015xx series provides 150 mA maximum current from an input voltage ranging from 1.5 V to 5.5 V with a typical dropout voltage of 80 mV. It is stable with ceramic capacitor. The ultra-low drop voltage, low quiescent current and low noise features make it suitable for low power battery-powered applications.

Features

■ Ultra low dropout voltage (80 mV typ. at 100 mA load)

■ Very low quiescent current (18 µA typ. at no load, 35 µA typ. at 150 mA load, 1 µA max in off mode)

■ Very low noise without bypass capacitor (29 µVRMS at VOUT = 0.8 V)

■ Output voltage tolerance: ± 2.0 @ 25 °C

■ 150 mA guaranteed output current

■ Wide range of output voltages available on request: 0.8 V to 3.3 V with 100 mV step

■ Logic-controlled electronic shutdown

■ Compatible with ceramic capacitors CO = 1 µF

■ Internal current and thermal limit

■ Available in SOT666 and SOT23-5L packages

■ Temperature range: -40 °C to 125 °C

LD39015XG08R属于集成电路（IC） > 线性 + 开关稳压器。意法半导体（ST）集团制造生产的LD39015XG08R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。
