LT3061 是一款微功率、低压差 (LDO) 线性稳压器,其工作在一个 1.6V 至 45V 的电源范围内。该器件可提供 100mA 的输出电流和一个 250mV 的典型压差电压。单个外部电容器提供了可编程低噪声基准性能和输出软起动功能。LT3061 的静态电流仅为 45μA,并利用一个最小 3.3μF 的输出电容器实现了快速瞬态响应。在停机模式中,静态电流小于 3μA,而且基准软起动电容器复位。
LT3061 具有一个 NMOS 下拉电阻器,这负责在 SHDN 或 IN 被驱动至低电平的情况下对输出进行放电。
内部保护电路包括反向电池保护、反向电流保护、具折返的电流限制和热停机。
LT3061 具有可用的 3.3V 和 5V 固定输出电压,并且可以用作一款具有一个从 600mV 基准至高达 19V 输出电压范围的可调型器件。LT3061 采用耐热性能增强型 8 引脚 2mm x 3mm DFN 封装和 MSOP 封装。

DC2177A-A:LT3061 Demo Board | Micropower, Low Noise LDO with Output Discharge, 2.1V ≤ VIN ≤ 45V, VOUT = 1.2V to 5V @ 100mA
Demonstration circuit 2177A-A features the LT3061, a micropower, low noise and low dropout voltage linear regulator with output discharge. The input voltage ranges from 2.1V to 45V and the maximum output current is 100mA. A resistor divider determines the output voltage, and a jumper adjusts the divider to set the output voltage to either 1.2V, 1.5V, 1.8V, 2V, 2.5V, 3.3V, 5V or a voltage that is user-programmed but requires the installation of a resistor. The output uses a 10μF ceramic capacitor and the internal reference is bypassed with a 10nF capacitor to reduce output noise and program the soft-start. There is also a 10nF feedforward capacitor to improve load transient response and decrease noise at higher output voltages. The position of the VOUTEN jumper either pulls up the SHDN pin to the input supply through a 100k resistor, shorts SHDN to ground or floats the SHDN pin so it can be driven directly by a signal applied to the SHDN terminal.
