NCP51460中文资料精确电压参考，20 mA，低 Iq，高 PSRR，低噪声数据手册ONSEMI规格书

描述 Description

The NCP51460 is a high performance, low power precision voltage reference. It can supply output current up to 20 mA at a 3.3 V fixed output voltage. Excellent line and load regulation characteristics, very good PSRR, low Output Noise and low Quiescent Current makes the NCP51460 ideal for precision regulator applications. The device is designed to be stable without an output capacitor. This feature makes the device ideal for space constrained applications. An optional output capacitor may be added to improve the load transient response. Protective features include Short Circuit and Reverse Input Voltage Protection. In the case of reverse input voltage connection the reference will not conduct any current protecting the device from damage. The NCP51460 is packaged in a 3-lead surface mount SOT-23 package.

简介

NCP51460属于集成电路（IC）的电压基准。由制造生产的NCP51460电压基准产品属于基准电压源系列，可通过相对较不稳定的电源提供稳定的电势，电压值始终保持恒定，以便在测量、控制和类似应用中用作比较的标准。其功能行为可能与用于大功率调节的线性稳压器相似，但基准电压源器件却不适合用于此类用途。用作比较标准时，若输出电流容量或实际负载电流增大，其性能通常会降低。
