What are the key features of TLV74311PDBVR?

Ultra-low dropout voltage of 122 mV typical at 300 mA output current, minimizing power dissipation in battery-powered designs
Wide input voltage range of 1.4 V to 5.5 V, compatible with single-cell Li-ion and multi-cell alkaline battery supplies
Compact SOT-23-5 package enabling high-density power rail integration in space-constrained portable and wearable electronics

What is TLV74311PDBVR used for?

The TLV74311PDBVR is ideal for powering low-voltage microcontrollers, wireless SoCs, and sensor modules in battery-operated portable devices where minimizing voltage headroom is critical. Its low 122 mV dropout voltage extends battery run time by allowing operation close to the battery's discharge cutoff. The device also suits always-on IoT nodes and wearable health monitors that require a stable low-noise 3.3 V or lower rail from a single-cell supply.

Frequently Asked Questions

What is the maximum output current the TLV74311PDBVR can supply to a load?

The TLV74311PDBVR is rated for a maximum continuous output current of 300 mA. This is sufficient to power microcontrollers, BLE SoCs, and mixed-signal peripherals, while keeping the SOT-23-5 package within its thermal envelope at typical ambient temperatures up to 85°C.

How low is the dropout voltage of the TLV74311PDBVR at full rated current?

At 300 mA output current, the TLV74311PDBVR achieves a typical dropout voltage of just 122 mV, with an absolute maximum of 480 mV. This ultra-low dropout allows the device to regulate down to within 122 mV of the battery rail, extending usable run time on 3.7 V Li-ion cells.

Can the TLV74311PDBVR operate from a single-cell Li-ion battery throughout its full discharge cycle?

Yes. Because the TLV74311PDBVR accepts an input voltage as low as 1.4 V and as high as 5.5 V, it can maintain regulation from a fully charged 4.2 V Li-ion cell all the way down to the cell's 3.0 V cutoff, providing a stable output for at least 1800 mAh per charge cycle in typical applications.

What output voltage options are available for the TLV74311PDBVR in the fixed-output family?

The TLV74311PDBVR is a fixed-output device in the TLV743xx family; Microchip offers multiple fixed output voltage variants ranging from 1.0 V to 3.3 V in 100 mV steps, with each variant sharing the same SOT-23-5 footprint and 300 mA current rating for easy design migration.
