ADM7160 Powering a 16-Bit/18-Bit ADC GENERAL DESCRIPTION The ADM7160 is an ultralow noise, low dropout linear regulator that operates from 2.
2 V to 5.
5 V and provides up to 200 mA of output current.
The low 150 mV dropout voltage at 200 mA load improves efficiency and allows operation over a wide input voltage range.
Using an innovative circuit topology, the ADM7160 achieves ultralow noise performance without the need for a bypass capacitor, making the device ideal for noise-sensitive analog front-end and RF applications.
The ADM7160 also achieves ultralow noise performance without compromising PSRR or transient line and load performance.
Current-limit and thermal overload protection circuits prevent damage under adverse conditions.
The ADM7160 also includes an internal pull-down resistor on the EN input.
The ADM7160 is specifically designed for stable operation with tiny 1 µF, ±30% ceramic input and output capacitors to meet the requirements of high performance, space constrained applications.
The ADM7160 is available in tiny 5-lead TSOT and 6-lead LFCSP packages with 16 fixed output voltage options, ranging from 1.
1 V to ...
