Overview
The LT1962 series, produced by Linear Technology (now part of Analog Devices), are micropower, low noise, low dropout linear regulators. These devices are designed to supply up to 300mA of output current and feature a low dropout voltage of 270mV. They are available in fixed output voltages of 1.5V, 1.8V, 2.5V, 3V, 3.3V, and 5V, as well as an adjustable version with a 1.22V reference voltage. The regulators are packaged in an 8-lead MSOP package, making them suitable for a variety of applications where space is limited.
