TLV73311PDBVT Integrated Circuits (ICs)

TLV73311PDBVT (Texas Instruments) is a CMOS linear Voltage Regulator, specifically a Low Quiescent Current Low Dropout Voltage Regulator. It is designed for use in battery-operated and power sensitive applications, providing excellent transient response, very low dropout voltage and a wide range of operating input voltage. The TLV73311PDBVT is a high efficiency low dropout regulator built into a Pb-free 5-pin SOT-23 package, making it ideal for applications where space is a primary concern.

The TLV73311PDBVT is able to provide power for 1.2 V to 3.6 V systems. It can be used as an output regulator for a full range of voltages from 1.5 V to 5.5 V, and a maximum output current of 800 mA. The TLV73311PDBVT can be used to regulate both fixed and adjustable outputs. It features low input/output voltage differences, under 0.3 V, allowing for up to 95% efficiency. This increased efficiency reduces power consumption, making the TLV73311PDBVT perfect for portable and battery-powered products. The TLV73311PDBVT also includes internal Thermal Shutdown, and Reverse Current Protection, ensuring safe operation in the event of system overload.

The TLV73311PDBVT operates using a fixed-frequency, pulse-width modulation (PWM) control scheme. This requires a resistive voltage divider which provides the reference voltage to the chip’s non-inverting input pin. The reference voltage determines the output voltage. The Error Amplifier then checks the output voltage versus the reference voltage and adjusts the duty cycle of the internal PWM control circuit to correct any deviation.

The TLV73311PDBVT is well suited for a variety of applications such as notebook computers, PDAs, cellular phones, and other devices where space, power requirements, and low quiescent current are of concern. Its tiny 5-pin SOT-23 package and very low power dissipation make it an attractive component for small form factor designs.

In summary, the TLV73311PDBVT is an excellent low dropout linear voltage regulator with high efficiency, low operating current and wide adjustable voltage ranges. It is built into a small-sized 5-pin SOT-23 package, making it very suitable for small form factor designs. It is a great choice for applications in which low-power dissipation, low quiescent current, and small size are of primary importance.
