LT3063 是一款微功率、低压差 (LDO) 线性稳压器,其工作在 1.6V 至 45V 的电源范围,它具有固定输出系列和可调版本。该器件可提供 200mA 的输出电流和一个 300mV 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。LT3063 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。
LT3063 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。
LT3063 具有 3.3V 和 5V 的固定输出电压,并且可用作具 600mV 基准到高达 19V 输出电压范围的可调器件。LT3063 采用耐热增强型 8 引脚 2mm x 3mm DFN 和 MSOP 封装。

DC2177A-C:LT3063演示板 | 具有输出放电功能的低噪声LDO,2.1V ≤ VIN ≤ 45V,VOUT = 1.2V/1.5V/1.8V/2V/2.5V/3.3V/5V/可调(200mA)
演示电路2177A-C内置LT3063,一款具有有源输出放电功能的微功耗、低噪声和低压差线性稳压器。输入电压范围是2.1V至45V且最大输出电流为200mA。电阻分压器可确定输出电压,且跳线调整分压器将输出电压设置为1.2V、1.5V、1.8V、2V、2.5V、3.3V、5V或用户编程值,但需要安装电阻。该输出使用10μF陶瓷电容,且内部基准电压源使用10nF电容进行旁路以降低输出噪声并对软启动进行编程。还提供10nF前馈电容,以便在较高的输出电压下改善负载瞬态响应并降低噪声。VOUTEN跳线位置通过100k电阻将SHDN引脚上拉至输入电源,将SHDN对地短路或将SHDN引脚浮空,以便可通过施加到SHDN端子的信号直接驱动。LT3063的输入电源通过2.2μF陶瓷电容进行旁路,输入上还提供50V钽聚合物电容以便抑制使用长引线对输入进行热插拔时可能发生的振铃。
DC2177A:LT3063 Demo Board | Low Noise LDO with Output Discharge, 2.1V ≤ VIN ≤ 45V, VOUT = 1.2V to 5V @ 200mA
Demonstration circuit 2177A-C features the LT3063, 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 200mA. 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. The input supply to the LT3063 is bypassed by a 2.2μF ceramic capacitor and there is also a 50V tantalum polymer capacitor on the input to dampen ringing that may occur when the input is hot-plugged using long leads.
