Analog Devices Inc. Discrete Pass Element LDO Linear Regulators

Analog Devices Inc. Discrete Pass Element LDO Linear Regulators are a broad line of high-performance low-dropout linear regulators with very low dropout and fast transient response. The Analog Devices regulators offer excellent line and load regulation and have a very wide 0.9V to 80V input voltage range. Output currents range from 100mA to 10A, with positive, negative, and multiple outputs.
