LDO Linear Regulators

Analog Devices manufactures a broad line of high performance low dropout (LDO) linear regulators. These LDO regulators offer very low dropout, fast transient response, and excellent line and load regulation, and they have a very wide input voltage range (0.9 V to 80 V). Output currents range from 100 mA to 10 A, with positive, negative, and multiple outputs. Our LDO+ devices provide additional functionality and features beyond basic linear regulator performance. These may include voltage, current and temperature monitoring, diagnostic information, and features such as programmable current limit, active output discharge, or the ability to control an upstream supply powering the LDO device.
