NCP51460: Precision Voltage Reference, 20 mA Micropower
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.
