What are the key features of TLV74330PDQNR?
- 300 mA output at fixed 3.3 V with only 122 mV typical dropout voltage, allowing operation from 3.5 V input near full discharge of a Li-ion battery
- Ultra-low quiescent current in the microampere range for always-on power rail management in battery-powered IoT and wearable designs
- Compact 4-pin SOT-23 (SOT-N4) package occupying under 5 mm² of PCB area with minimal external components—only input and output bypass capacitors required
What is TLV74330PDQNR used for?
TLV74330PDQNR is used to generate a 3.3 V rail for microcontrollers, sensors, and Bluetooth SoCs in wireless sensor nodes, fitness trackers, and medical wearables powered by Li-ion cells. Its 122 mV typical dropout allows the 3.3 V output to remain in regulation until the battery discharges to approximately 3.4 V, maximizing usable battery runtime. The 4-pin SOT-23 package and single-supply operation simplify placement near the load in space-constrained PCB designs.

Frequently Asked Questions
What is the minimum input voltage needed to maintain a regulated 3.3 V output on TLV74330PDQNR?
With a 122 mV typical dropout voltage, TLV74330PDQNR requires a minimum input of approximately 3.42 V to hold the 3.3 V output in regulation. The device is rated for a 3.5 V minimum input in its specifications, giving a small margin that extends usable runtime for Li-ion batteries discharging from 4.2 V down toward 3.5 V.
How does the quiescent current of TLV74330PDQNR compare to a standard LDO for always-on IoT sensor nodes?
TLV74330PDQNR draws a quiescent current in the range of 1 µA to 25 µA depending on load, compared to 100 µA or more for older LDO topologies like the LP2950 series. For a 200 mAh coin-cell battery, reducing standby current from 100 µA to 25 µA can extend shelf life from roughly 3 months to over 12 months in deeply sleep-cycling IoT nodes.
For a compact BLE module power supply, what external components does TLV74330PDQNR require?
TLV74330PDQNR needs only a 1 µF ceramic capacitor on the input and a 1 µF ceramic capacitor on the output for stable operation, with no external resistors needed for the fixed 3.3 V version. This 2-component BOM, combined with the 4-pin SOT-23 package, occupies under 10 mm² of total PCB area—ideal for tight BLE or Zigbee module layouts.
