Key Features
- Dual 200 mA fixed 1.8 V LDO outputs with 150 mV typical dropout voltage at full load current
- High PSRR and low output noise make it ideal for noise-sensitive RF and analog supply rails
- Compact 6-pin SOT-23 (S-PDSO-N6) package with 2 V to 5.5 V input range for battery-powered designs
Applications
The TLV7103318DSET is designed for portable and IoT devices where a clean, stable 1.8 V rail from a single-cell Li-ion or 3.3 V system supply is required. Its low 150 mV dropout and high PSRR suppress supply noise on sensitive analog and RF circuits, such as ADC reference rails and wireless transceiver VDDs. The dual-output capability allows one IC to power two independent 1.8 V domains, reducing BOM count in compact wearables and sensor nodes.

Frequently Asked Questions
What is the dropout voltage and output current of the TLV7103318DSET under full load?
The TLV7103318DSET has a typical dropout voltage of 150 mV and a maximum of 200 mV at the full 200 mA output current per channel. This low dropout allows the regulator to maintain a stable 1.8 V output from an input as low as 2 V, extending battery life in single-cell Li-ion powered designs to near-complete cell discharge.
What input voltage range does the TLV7103318DSET accept, and is it compatible with 3.3 V logic supply rails?
The TLV7103318DSET accepts input voltages from 2 V to 5.5 V (absolute maximum 6 V), making it directly compatible with 3.3 V and 5 V system supply buses. With a 3.3 V input and 1.8 V output, the headroom is 1.5 V — well above the 200 mV maximum dropout — ensuring stable regulation across load transients in mixed-voltage digital systems.
Which noise-sensitive applications benefit most from the TLV7103318DSET dual LDO?
RF transceivers, precision ADC reference supplies, and MEMS sensor interfaces benefit most because the TLV7103318DSET combines high PSRR (typically above 60 dB at 1 kHz) with low output noise below 30 µV RMS. These figures keep supply-induced spurs below the noise floor of 12-bit ADCs sampling at 1 MSPS and reduce phase noise on PLL and VCO supply pins.
How does the TLV7103318DSET compare to a single-output LDO when powering two 1.8 V rails on an IoT board?
Using a single TLV7103318DSET dual LDO instead of two separate regulators saves one component, reduces PCB area by approximately 30 mm2 for a 6-pin SOT-23 versus two SOT-23-5 parts, and lowers total BOM cost. Both 200 mA output channels share the same 2 V to 5.5 V input, so a single decoupling capacitor on the input bus serves both channels simultaneously.
