Frequently Asked Questions
What is the input voltage range for the TPS2141IPWPR?
The TPS2141IPWPR operates from an input voltage range of 4.1 V to 5.5 V, making it compatible with USB 5 V bus power and single-cell lithium-ion battery systems. The wide input range supports both direct USB power and regulated system supply rails in portable electronic applications.
What is the dropout voltage of the TPS2141IPWPR LDO?
The TPS2141IPWPR has a typical dropout voltage of 0.18 V and a maximum dropout voltage of 0.5 V, allowing the output to remain regulated even when the input voltage is very close to the output voltage. This low dropout performance is essential for battery-powered applications where maximizing usable battery capacity is important.
Does the TPS2141IPWPR have current limiting protection?
Yes, the TPS2141IPWPR features dual current limiting for both the LDO output and the 5 V switch output, protecting downstream circuits from overcurrent damage. The dual current limit configuration allows independent protection thresholds for each output, preventing single-fault conditions from affecting both power rails simultaneously.
What package does the TPS2141IPWPR use?
The TPS2141IPWPR is housed in a 14-pin TSSOP (Thin Shrink Small Outline Package) designated R-PDSO-G14. This compact surface-mount package minimizes PCB footprint while providing good thermal dissipation, making it suitable for space-constrained portable device power management designs.
What is the line regulation specification for the TPS2141IPWPR?
The TPS2141IPWPR achieves a maximum line regulation of 0.1% per volt, meaning the output voltage changes by no more than 0.1% for each 1 V change in input voltage. This excellent line regulation ensures stable power delivery to sensitive circuits even when input voltage fluctuates due to battery discharge or load transients.
