Key Features
- Dual independent LDO channels (300 mA and 150 mA) supply two separate voltage rails from a single 8-pin MSOP IC, reducing BOM count
- Ultra-low dropout of 104 mV typical on the main channel enables near-full utilization of Li-ion battery charge down to cell end-of-life
- CMOS architecture minimizes quiescent current consumption, extending battery runtime in portable Bluetooth, Wi-Fi, and cellular IoT modules
Applications
The TC1301A-ADAVUA is designed for portable consumer electronics and IoT devices requiring two regulated supply rails—such as a core voltage and an I/O voltage—from a single Li-ion or Li-polymer cell. Its 300 mA primary output powers processor cores and RF modules while the 150 mA secondary output supplies sensors and interface logic at a different voltage. The compact MSOP-8 footprint makes it a natural fit for wearables, wireless earbuds, and compact embedded modules.

Frequently Asked Questions
How low can the input voltage drop before TC1301A-ADAVUA fails to regulate its 300 mA output?
The TC1301A-ADAVUA main channel maintains regulation with only 104 mV typical dropout voltage across the 300 mA output. For a 3.3 V output rail, the input voltage can drop to approximately 3.4 V before regulation is lost, allowing it to operate from a Li-ion cell through most of its 3.6 V to 4.2 V discharge range without any loss of regulated output.
Can TC1301A-ADAVUA power both the MCU core (1.8 V, 200 mA) and I/O rail (3.3 V, 100 mA) simultaneously from a single 3.7 V Li-ion cell?
Yes. The TC1301A-ADAVUA provides 300 mA on its first channel and 150 mA on its second channel, which comfortably covers 200 mA at 1.8 V and 100 mA at 3.3 V simultaneously. With a 3.7 V Li-ion input and dropout voltages below 0.25 V on both channels, both outputs remain regulated throughout the battery's normal discharge from 4.2 V down to approximately 3.5 V.
How does the 8-pin MSOP package of TC1301A-ADAVUA compare to using two separate SOT-23 LDOs for dual-rail designs?
A dual SOT-23-5 LDO solution requires two separate ICs occupying roughly 2 × 9 mm² = 18 mm² of PCB area plus routing between them. The TC1301A-ADAVUA integrates both regulators in a single MSOP-8 package measuring approximately 4.9 mm × 3.0 mm (about 15 mm²), saving board area and reducing the number of discrete components by at least 50% including bypass capacitors and enable resistors.
