Key Features
- Ultra-low 0.28V nominal dropout voltage (0.5V max) at 500mA enables efficient regulation even with small input-output voltage differentials
- Adjustable output voltage from 2.7V to 6.5V input range with 0.02%/V maximum line regulation for precise and stable power supply performance
- Low quiescent current and low noise design in compact 8-pin SON package makes it ideal for noise-sensitive RF and analog signal chain applications
Applications
The TPS73501DRBR is designed for noise-sensitive applications including RF transceiver power supplies, analog-to-digital converter references, and precision sensor bias circuits requiring clean, stable voltage rails. Its low dropout of 0.28V and 500mA output current make it suitable for powering DSPs, FPGAs, and microcontrollers from single-cell Li-ion batteries or 3.3V-5V system rails. The adjustable output and low quiescent current profile support portable instrumentation and wearable electronics designs.

Frequently Asked Questions
What is the dropout voltage of the TPS73501DRBR at full load?
The TPS73501DRBR has a nominal dropout voltage of 0.28V and a maximum of 0.5V at 500mA output current, allowing it to maintain regulation even when the input voltage is only slightly higher than the output, which is critical for battery-powered applications.
What is the output current capability and input voltage range of the TPS73501DRBR?
The TPS73501DRBR can source up to 500mA of output current and accepts input voltages between 2.7V and 6.5V, making it compatible with a wide range of power sources including 3.3V, 5V rails, and single-cell lithium-ion batteries in portable electronics.
Is the output voltage of the TPS73501DRBR fixed or adjustable?
The TPS73501DRBR features an adjustable output voltage, allowing designers to set the regulated output using an external resistor divider network, providing flexibility to supply any voltage within the supported range for different subsystems in a design.
What package does the TPS73501DRBR use and is it RoHS compliant?
The TPS73501DRBR is available in an 8-pin SON (S-PDSO-N8) package with a small footprint, and is fully RoHS compliant as indicated by its lead-free code (Pbfree Code: Yes) and JESD-609 Code e4, suitable for green electronics manufacturing.
Why is the TPS73501DRBR suitable for RF and analog noise-sensitive circuits?
The TPS73501DRBR is specifically designed with low noise output and low quiescent current characteristics, which suppress power supply-induced noise that can degrade the performance of RF amplifiers, ADCs, PLLs, and precision analog circuits requiring clean voltage references.
