Frequently Asked Questions
What is the output voltage and maximum output current of the TPS73533DRBR?
The TPS73533DRBR provides a fixed 3.3V output with a maximum continuous output current of 500mA. The typical dropout voltage at full load is 280mV, with a maximum of 500mV, allowing the device to regulate down to a 3.8V input supply.
What input voltage range does the TPS73533DRBR support?
The TPS73533DRBR operates with an input voltage range of 3.8V to 6.5V, and the absolute maximum input voltage is 7V. This range is well-suited for single-cell Li-ion batteries (fully charged at ~4.2V) as well as 5V USB and regulated rail sources.
What package does the TPS73533DRBR use, and what are typical applications?
The TPS73533DRBR comes in an 8-pin VSON (DRB) package with an exposed thermal pad for improved heat dissipation. Typical applications include portable devices, wearables, IoT sensor nodes, RF front-ends, and precision analog circuits that require a low-noise 3.3V supply with minimal quiescent current.
Can the TPS73533DRBR replace a TPS73633 or similar LDO in my design?
The TPS73533DRBR is pin-compatible with other TPS735xx family members but is fixed at 3.3V. If your design uses a TPS73633 (3.6V) or another fixed variant, switching to the TPS73533 requires verifying that 3.3V meets your downstream component requirements. Electrically, dropout, quiescent current, and PSRR specifications remain the same across the family.
