Frequently Asked Questions
What is the dropout voltage of the TPS7A2033PDQNR?
The TPS7A2033PDQNR has a maximum dropout voltage of 140mV at 300mA output current. This ultra-low dropout characteristic allows the regulator to maintain a stable 3.3V output even when the input supply drops to as low as 3.6V, making it efficient for Li-ion battery-powered and USB-powered portable applications.
What is the maximum output current of the TPS7A2033PDQNR?
The TPS7A2033PDQNR provides a maximum output current of 300mA (0.3A) at a fixed 3.3V output. This current capacity is sufficient to power microcontrollers, wireless modules, sensors, and other low-power 3.3V digital and analog circuits found in IoT, wearable, and embedded system designs.
What package does the TPS7A2033PDQNR use and what are its dimensions?
The TPS7A2033PDQNR uses a 4-pin X2SON (S-PDSO-N4) package, an ultra-compact surface-mount package with an exposed thermal pad for improved heat dissipation. This miniature package is ideal for space-constrained PCB designs where minimal regulator footprint is required alongside efficient thermal management.
What is the input voltage range for the TPS7A2033PDQNR?
The TPS7A2033PDQNR accepts input voltages from 3.6V minimum to 6V maximum, with an absolute maximum of 6.5V. This range is compatible with common power sources including single-cell Li-ion batteries (nominally 3.7V to 4.2V), 5V USB rails, and regulated 5V power supplies, offering broad design flexibility.
