LT3015IQ#TRPBF

LT3015IQ#TRPBF Application Field and Working Principle

LT3015 are high-efficiency, low-noise and low dropout regulators (LDO). The LT3015IQ#TRPBF series comes with adjustable output voltage and a high power-supply range of up to 36V. This makes it ideally suited for accurate voltage regulation in applications with varying supply voltage, such as microcontrollers, embedded systems and power management ICs.

The LT3015IQ#TRPBF series has several key features that make it particularly suitable for low voltage power conversion design: high efficiency at low load, low quiescent current, low dropout voltage and minimized output voltage ripple and noise. The regulators incorporate both a 100 mA integrated transistor and a 0.1 ohm current-limiting resistor, and can be used for an output current of up to 1.5A for robust, reliable and accurate voltage regulation.

Working Principle of LT3015IQ#TRPBF

The LT3015IQ#TRPBF series is basically a low-dropout (LDO) linear voltage regulator with an adjustable output voltage. The regulator is based on a proprietary topology, which combines a voltage reference, an operational amplifier and a series pass transistor. It features excellent regulation, low dropout voltage, high efficiency and low current ripple at light loads.

The LT3015IQ#TRPBF operates by comparing an internal reference voltage to the feedback voltage on its output and subtracting the two values. The difference is amplified and then used to adjust the output voltage of the regulator. The output voltage is limited to a maximum of 36V, ensuring that the output voltage does not exceed this level under any condition.

The series pass transistor operates in constant-current mode and draws the load current from the input voltage. This topology ensures that the output voltage remains reasonably stable over the entire operating range of the regulator, even when the input voltage and load current are varying.

The LT3015IQ#TRPBF incorporates several protection features that prevent damage to the device in case of over current or over voltage. The device also has an internal thermal shutdown feature which protects the device from thermal overload.

Overall, the LT3015IQ#TRPBF series is an excellent choice for applications that require low-noise, low-dropout and high-efficiency power conversion. The device is suitable for use in a wide variety of applications such as microcontroller-based systems, embedded systems and power management ICs.
