What are the key features of TPS709B33DBVT?
- Ultra-low quiescent current for minimal standby power drain in always-on battery systems
- Wide 2.7 V to 30 V input range supports automotive, industrial, and multi-chemistry battery inputs
- Reverse current protection prevents damage when output voltage exceeds input
- 0.3 V typical dropout voltage maximizes efficiency and extends battery operating time
What is TPS709B33DBVT used for?
The TPS709B33DBVT is ideal for always-on IoT nodes, remote sensors, and wearable devices where standby quiescent current directly determines battery life in sleep modes. Its wide 30 V input range suits automotive 12 V and 24 V systems, as well as industrial equipment powered from unregulated supplies. The reverse current protection feature makes it suitable for applications with potential back-drive conditions such as multi-rail power sequencing and hot-swap designs.

Frequently Asked Questions
What is the input voltage range of the TPS709B33DBVT?
The TPS709B33DBVT accepts input voltages from 2.7 V to 30 V, making it one of the widest-range LDO regulators in its class. This allows use with automotive 12 V / 24 V batteries, industrial power supplies, and multi-chemistry lithium battery stacks with significant headroom for transient overvoltages.
Why is ultra-low quiescent current important in the TPS709B33DBVT?
Ultra-low quiescent current (Iq) means the TPS709B33DBVT draws very little current from the supply when no load is present. In battery-powered IoT sensors and wearables that spend most of their time in sleep mode, a lower Iq directly extends battery life, potentially by months or years in coin-cell-powered applications.
What is reverse current protection in the TPS709B33DBVT and when is it needed?
Reverse current protection prevents current from flowing backward from the output to the input when the output voltage is higher than the input — a condition that can occur during power sequencing, hot-swap, or when multiple supplies share a common output rail. Without this protection, reverse current could damage the LDO or disrupt other system voltages.
What is the dropout voltage of the TPS709B33DBVT?
The TPS709B33DBVT has a typical dropout voltage of 0.3 V and a maximum of 1.4 V at full 150 mA load. Low dropout means the input can be as low as 3.6 V (3.3 V + 0.3 V typical) while still maintaining regulation, extending usable range as battery voltage decreases.
What package does the TPS709B33DBVT use?
The TPS709B33DBVT is housed in a 5-pin SOT-23 (R-PDSO-G5) surface-mount package, one of the smallest standard packages available for LDO regulators. Its compact footprint is ideal for space-constrained designs in wearables, hearing aids, miniature sensors, and compact industrial modules.
