It shares an excellent combination of features that include a wide input voltage range (2.5V to 24V), and fixed output voltage options of 1.2V, 1.8V, 2.5V and adjustable down to 1.22V. The output current of up to 1.3A and extremely low dropout voltage of 165mV make the LT3012BEDE#TRPBF an ideal choice for a wide range of applications.

As part of the PMIC - Voltage Regulators - Linear family, the LT3012BEDE#TRPBF stand out with it’s high performance and features. The device features an internal current limiting output transistor, which works with the temperature shutdown circuit to prevent excessive dissipation during overloads. It also boasts an internal reverse current block that guarantees thermal protection during reverse battery condition. With its reverse operation capability, the device ensures a reliable operation in series circuits.

In terms of working principle, the LT3012BEDE#TRPBF is based on the principles of series linear regulation, the main elements of which is a transistor, a diode, a resistor and a capacitor. The transistor is the main element that carries out the actual regulating action, and by controlling its base current, a precise voltage is maintained across the load. The transistor acts as a variable resistor, and its resistance is determined by the amount of base current it is subjected to. The diode is also important, as it prevents the flow of too much current into the base of the transistor.

The resistor is used to determine how much current flows through the transistor, and the capacitor is a filter to help reduce the ripple in the output voltage. The fundamental principle of operation of a series linear regulator is to keep the output voltage at a set value by allowing a certain amount of current to flow through the transistor and adjusting this current as the input or output voltage changes. In practice, the resistors and capacitors are connected in a feedback network in order to closely control the current flow.

In addition, the LT3012BEDE#TRPBF includes an internal first stage current source to provide better line regulation by providing additional current while the operating voltage is changing. As a result, with its excellent combination of features, the LT3012BEDE#TRPBF is an ideal choice for a wide range of applications, especially those where low current consumption and fast transient response are required.
