UC2836中文资料36V 可调节线性稳压器数据手册TI规格书

描述 Description

The UC1835/6 families of linear controllers are optimized for the design of low cost, low dropout, linear regulators. Using an external pass element, dropout voltages of less than 0.5V are readily obtained. These devices contain a high gain error amplifier, a 250mA output driver, and a precision reference. In addition, current sense with fold-back provides for a 2.5A peak output current dropping to less than 0.5A at short circuit. These devices are available in fixed, 5V, (UC1835), or adjustable, (UC1836), versions. In the fixed 5 volt version, the only external parts required are an external pass element, an output capacitor, and a compensation capacitor. On the adjustable version the output voltage can be set anywhere from 2.5V to 35V with two external resistors.Additional features of these devices include under-voltage lockout for predictable start-up, thermal shutdown and short circuit current limiting to protect the driver device. On the fixed voltage version, a reverse voltage comparator minimizes reverse load current in the event of a negative input to output differential.

简介

UC2836属于集成电路（IC）的线性稳压器。由TI制造生产的UC2836稳压器 - 线性稳压器控制器线性电压调节是指使用与负载串联的旁路元件（通常是双极型或场效应晶体管）以及对应的驱动控制电路，以在负载两端产生恒定的标称电压，负载通常对电路的电源电压变化或负载电流不敏感。该系列中的产品提供与外部旁路元件配合使用所必需的控制功能，从而将其与集成线性稳压器区分开来，后者将旁路元件与控制电路整合在单个器件封装中。
