Key Features
- Ultra-low 1 µA quiescent current extends battery life in always-on IoT and wearable applications
- 150 mA output current with only 245 mV typical dropout voltage at full load
- Tiny 6-pin SON package (1.5 mm x 1.5 mm) minimises board area in portable designs
Applications
The TPS70633DRVR is an ideal power supply solution for battery-operated devices such as wearables, wireless sensors, and IoT modules that demand extremely low quiescent current to extend shelf life. Its 3.3 V fixed output directly powers microcontrollers and low-power radios operating from Li-ion or two-cell AA battery stacks. The 6-pin SON footprint also fits tight PCB areas in smartcard readers and compact medical monitoring patches.

Frequently Asked Questions
How low is the quiescent current of TPS70633DRVR and how does that benefit battery-powered designs?
The TPS70633DRVR draws only 1 µA quiescent current under no-load conditions. In a coin-cell-powered sensor running mostly in sleep mode, this means the regulator alone contributes less than 8.76 mAh of drain per year, significantly extending shelf life compared to regulators with 50 µA to 100 µA standby current.
What is the input voltage range and what dropout voltage can be expected at full 150 mA load?
The device accepts input voltages from 4.3 V to 6.5 V with an absolute maximum of 7 V. At the rated 150 mA output, the maximum dropout voltage is 1.54 V, while the nominal dropout is only 245 mV, allowing the regulator to sustain a 3.3 V output from a nearly depleted Li-ion cell.
When would a designer choose TPS70633DRVR over a standard LDO with higher quiescent current?
Designers select the TPS70633DRVR whenever the load is mostly in standby, such as in wireless sensor nodes that wake every 10 minutes to take a 1 ms measurement. With 1 µA quiescent current versus a typical 100 µA competitor, the annual standby drain drops from roughly 876 mAh to 8.76 mAh, enabling designs to run years on a 250 mAh CR2032 cell.
