TPS75615KCG3

TPS75615KCG3 is a positive fixed voltage linear regulator, which integrates an internal power transistor, voltage reference, current limit and error amplifier, it is specifically designed for applications where low dropout and low noise are required.

It is classified as a PMIC (Power Management Integrated Circuit) - Voltage Regulators - Linear. It is designed to produce a stable, low-noise output voltage with a wide range of input voltage, suitable for systems with less than perfect power sources.

The TPS75615KCG3 is available in fixed-output voltage versions with either a 0.4V, 0.8V, 1.2V, 1.5V, 1.8V, 2.5V, 3V, 3.3V or 5V output. It can deliver up to 500 mA output current at a 240mV typical dropout voltage, when the input voltage is not less than 2V and 0.5V lower than the output voltage. Typical dropout voltage drops to 200mV when the input voltage is greater than 2.5V.

The device includes short-circuit protection and current-limit protection, as well as thermal shutdown protection, which helps prevent device damage. Other features include excellent load and line regulation, low noise (not more than 40µVRMS), high PSRR (not less than 70dB at 1kHz) and low quiescent current (not more than 10µA). The device also supports external shutdown control and wakeup functions.

When working, the internal voltage reference provides a reference voltage for the error amplifier, which adjusts the gate voltage of power transistor to control the output voltage. The output voltage is determined by the relation between the internal voltage reference and the external resistor information, and it will not be affected by the temperature.

TPS75615KCG3 can be widely used in various fields. It can be used in USB applications, such as a USB charger, or in battery-driven systems where the output voltage is well-regulated. Also, it can be applied to LED driver systems, powering fixed output controllers that maintain high-end LED brightness. It can also be used in consumer applications such as cameras, phones, routers, and so on. In automotive applications, it can be used in ADAS systems to provide stable voltage and current.

In summary, the TPS75615KCG3 is a positive fixed voltage linear regulator, which is ideal for applications requiring low dropout voltage and low noise. This PMIC can be used in a variety of applications, such as consumer electronics, automotive systems and so on, and it offers many advantages and protections including excellent load and line regulation, low noise, high PSRR and low quiescent current.
