PMIC - Voltage Regulators - Linear: TS90135CW RPG Application Field and Working Principle

The TS90135CW RPG linear voltage regulator is a high-precision, low-noise low dropout (LDO) voltage regulator. It is a 3-terminal device designed to provide a stable, low noise output voltage from a wide range of input voltages. This linear voltage regulator is specifically designed for use in space-limited, power-sensitive applications such as portable handheld electronics, cell phones, digital cameras and other portable consumer electronics.

The TS90135CW RPG linear voltage regulator is capable of providing a stable output voltage over a wide input voltage range of 1.3V to 5.0V, with currents up to 1.5A. The output voltage is adjustable from 0.8V to 4.5V, allowing for a wide range of flexibility in your power supply needs. This voltage regulator also has wide bandwidth and low output resistance, which allows it to maintain its output voltage with changing input voltages.

The working principle of the TS90135CW RPG linear voltage regulator is based on a third order low pass active filter. This active filter uses three active stages of transistors setup as an integrator, a gain amplifier and a compensator. This allows the regulator to reject high frequency input noise and maintain a stable output voltage as the input voltage varies. The low noise performance is further enhanced through the use of special input/output capacitors.

The TS90135CW RPG linear voltage regulator features a current protection feature which limits the current through the device if the voltage is too high or low. This feature helps to protect the device from over voltage conditions and helps to maintain its performance over time. Additionally, this device is capable of providing a very low output noise level, making it suitable for high precision and low noise applications.

The TS90135CW RPG linear voltage regulator also features thermal protection. This feature helps to protect the device from thermal damage due to overload or over temperature conditions. Additionally, this device also features a power-saving mode which helps to reduce the amount of power consumption when the device is idle.

In summary, the TS90135CW RPG linear voltage regulator is a high precision, low noise LDO voltage regulator with wide operating temperature range and low output resistance. It is specifically designed for space-limited and power-sensitive applications, and provides excellent protection against overvoltage and over-temperature conditions. It is an ideal choice for portable consumer electronics, digital cameras and other applications which require a stable and clean voltage source.
