Analog Devices Inc. ADP176x CMOS Linear Regulators

Analog Devices ADP176 CMOS Linear Regulators product line includes low noise, Low Dropout (LDO) linear regulators. The ADP176 regulators operate from a single input supply voltage as low as 1.10V and offer up to 5A of output current. The design of these regulators eliminates the requirement for an external bias supply to improve efficiency. ADP176's low dropout voltage enables the regulators to operate with minimal board space, maintain regulation, and improve efficiency. The regulators are optimized for stable operation with small 10μF ceramic output capacitors. As a result, the ADP176 delivers optimal transient performance even with minimal board space. The ADP176 Regulators are housed in a small 16-lead LFCSP package to provide a small footprint solution to meet the requirements of a wide range of applications.
