Frequently Asked Questions
What is the typical dropout voltage of the TPS7433DR?
The TPS7433DR has a typical dropout voltage of 180 mV and a maximum dropout voltage of 315 mV at full load. This ultra-low dropout characteristic makes it ideal for battery-powered applications where the supply voltage is close to the regulated output voltage, maximizing usable battery runtime.
What is the input voltage range of the TPS7433DR?
The TPS7433DR operates with an input voltage range from 3.714V minimum to 7V maximum, with an absolute maximum rating of 8V. This range accommodates single-cell lithium-ion batteries, standard 5V USB supplies, and regulated bus voltages commonly used in portable and embedded systems.
Is the TPS7433DR adjustable or fixed output?
The TPS7433DR provides a fixed output voltage, meaning the output voltage is set internally and does not require external feedback resistors to set the regulation level. This simplifies the bill of materials and eliminates resistor tolerance errors, resulting in more predictable output voltage accuracy.
What package is the TPS7433DR available in?
The TPS7433DR is housed in an 8-pin Small Outline IC (SOIC) package, designated PDSO-G8. This is a standard surface-mount package with 1.27 mm pin pitch, making it straightforward to assemble using automated pick-and-place and reflow soldering processes.
What are typical applications for the TPS7433DR?
The TPS7433DR is used in battery-powered portable electronics, IoT sensors, wearables, and embedded microcontroller supply rails. It is also suitable for post-regulation following switching converters to reduce output noise, and in low-power instrumentation circuits requiring clean, stable supply voltages.
