Product Details
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 it 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 3.3 V. The LFCSP offers a very compact solution that provides excellent thermal performance for applications that require up to 200 mA of output current in a small, low profile footprint.
Applications
- ADC/DAC power supplies
- RF, VCO, and PLL power supplies
- Post dc-to-dc regulation
