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 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.
