Application Field

The LT3060MPTS8-5#TRPBF is a versatile voltage regulator that is ideally suited to driving a wide range of applications requiring low dropout (LDO) linear regulation. The wide input range of 4.5V to 30V, adjustable output options (1.2V to 30V), low quiescent current (2–10mA depending on output voltage) and fast load response make the LT3060MPTS8-5#TRPBF suitable for portable and non-portable devices. Applications include powering hard disks, CPU voltage regulation in computer motherboards, and fixed voltage regulation in industrial control circuits, portable electronics, and instrumentation modules.

Thanks to its integrated MOSFET switch and optimized RFI protection, the LT3060MPTS8-5#TRPBF is an excellent choice for point-of-load regulators, as well as systems that require an FPGA switching solution. It can even be used to tightly regulate the voltage output of a PIN diode. The LT3060MPTS8-5#TRPBF\'s low-noise design also makes it suitable for sensitive analog signals.

Working Principle

The LT3060MPTS8-5#TRPBF is an adjustable two-terminal linear regulator with an integrated MOSFET switch. Its primary features include low quiescent current, low dropout voltage and high accuracy voltage regulation. Its integrated MOSFET switch allows current-mode control, which can reduce noise, improve transient regulation and enhance system efficiency.

The LT3060MPTS8-5#TRPBF is based on a current-mode, inverting topology, which acts much like a switched capacitor buck regulator. Current is supplied from the input to the output via an integrated MOSFET switch. On the signal side, the voltage across the sense resistor is buffered and amplified, and the signal is used to control the power switch. When the output voltage deviates from the setpoint, the control circuitry reacts by adjusting the on-time of the switch for precise voltage regulation.

The LT3060MPTS8-5#TRPBF also features EMI protection with an integrated series latch and logic-compatible enable/disable function. This improved isolation between the input and output reduces the presence of any RF noise and interference, which is especially beneficial in embedded or sensitive circuits. Finally, the device also includes over-current protection, over-voltage protection and reverse current protection.

All in all, the LT3060MPTS8-5#TRPBF is a versatile voltage regulator that can be used for a variety of applications. It offers low quiescent current, wide input range, adjustable output, and fast load response. In addition, its integrated series latch and EMI protection offer improved noise immunity and isolation, making it an ideal choice for a wide range of applications.
