Key Features
- Industry-leading 200 nA quiescent current maximizes battery runtime in always-on IoT sensor nodes and energy-harvesting designs
- Fixed 0.9 V output with 205 mV typical dropout voltage supports sub-1 V core supply rails in ultra-low-power MCUs and SoCs
- Enable pin allows the host MCU to power-gate peripheral rails, cutting system standby current to near zero in duty-cycled applications
Applications
The TPS7A0309PDBVR is purpose-built for ultra-low-power IoT devices, wireless sensor nodes, and energy-harvesting systems where the regulator quiescent current dominates total standby power. Its 200 nA IQ and 0.9 V fixed output make it a direct supply for ultra-low-voltage microcontrollers and SoC core rails without wasting precious harvested energy. The 5-pin SOT-23 package with enable control fits easily onto coin-cell-powered PCBs and flexible hybrid electronics.

Frequently Asked Questions
How does the 200 nA quiescent current of TPS7A0309PDBVR extend battery life compared to a typical 50 µA LDO?
At 200 nA IQ versus a typical 50 µA LDO, the TPS7A0309PDBVR draws 250 times less standby current. On a 225 mAh CR2032 coin cell, that difference equates to roughly 128 years of quiescent-only run time for the TPS7A0309PDBVR versus just 5 months for the higher-IQ part, making nanopower operation critical in always-on sensing applications.
Which sub-1 V core supply rails can TPS7A0309PDBVR regulate for ultra-low-power SoCs?
The TPS7A0309PDBVR provides a fixed 0.9 V output at up to 200 mA, directly powering the core voltage rails of ultra-low-power SoCs and microcontrollers such as those in the MSP430, CC2340, or ARM Cortex-M0+ families. Its 205 mV typical dropout means a 1.1 V input is sufficient to maintain regulation, enabling efficient use of heavily discharged coin cells or thin-film batteries.
How does the enable pin on TPS7A0309PDBVR help reduce system power consumption in duty-cycled IoT designs?
The active-high enable pin lets the system MCU assert a logic signal to completely shut down the LDO output, cutting load-rail current to essentially 0 mA during sleep phases. In a duty-cycled sensor node that wakes every 10 seconds for a 10 ms measurement burst, gating the 0.9 V peripheral rail via enable can save tens of µAh per day compared to leaving the rail always on.
What input voltage range does TPS7A0309PDBVR support and which battery types are compatible?
The TPS7A0309PDBVR operates from 1.5 V to 6 V input voltage, making it compatible with single-cell Li-ion (3.0 V to 4.2 V), two alkaline AA cells in series (approximately 2.4 V to 3.2 V), CR2032 coin cells (2.0 V to 3.0 V), and 3.3 V or 5 V system rails. The wide input range and low 1.5 V minimum supply help extend usable discharge depth on primary batteries.
