Key Features
- Dual independent LDO outputs of 300 mA and 150 mA with only 104 mV typical dropout voltage for efficient low-headroom operation
- Input voltage range from 2.7 V to 6 V supports single-cell Li-ion and multi-cell alkaline battery-powered portable device designs
- Ultra-compact 8-pin DFN package with fixed output voltages minimizes PCB footprint in space-constrained mobile and wearable applications
Applications
The TC1301B-APAVMFTR is ideal for portable consumer electronics such as smartphones, tablets, and wearables requiring two independent regulated supplies from a single Li-ion battery with minimal power loss. Its 104 mV typical dropout voltage maximizes usable battery capacity when the input voltage is only slightly above the desired output rail. The device also suits audio codec power supplies, Bluetooth module rails, and sensor subsystem voltage domains where dual LDO regulation from 2.7 V to 6 V input must coexist in an 8-pin DFN footprint.

Frequently Asked Questions
What output current levels does TC1301B-APAVMFTR provide and how are the two channels typically used in a design?
TC1301B-APAVMFTR provides a 300 mA primary LDO output and a 150 mA secondary LDO output simultaneously. In portable designs, the 300 mA channel typically powers the application processor core or RF transceiver, while the 150 mA channel supplies lower-current peripherals such as sensors, audio codecs, or display controllers, both regulated independently from a shared 2.7 V to 6 V input supply.
How does TC1301B-APAVMFTR's 104 mV dropout voltage benefit single-cell Li-ion battery life compared to standard LDOs?
With only 104 mV typical dropout voltage, TC1301B-APAVMFTR continues regulating when the Li-ion cell discharges to within 104 mV above the output rail, extending usable runtime compared to standard LDOs requiring 300 mV or more of headroom. For a 3.3 V output rail, the regulator stays in regulation until the battery drops to approximately 3.4 V, recovering significant energy from the tail of the discharge curve.
In a Bluetooth or Wi-Fi IoT module design, why choose TC1301B-APAVMFTR over two discrete single-output LDOs?
TC1301B-APAVMFTR integrates two fixed-output LDOs rated at 300 mA and 150 mA into a single 8-pin DFN package, saving approximately 50% PCB area compared to two separate SOT-23 LDO regulators. The fixed output configuration reduces BOM by eliminating external resistor dividers, and the 2.7 V minimum input rating matches the end-of-life voltage of a Li-ion cell for IoT devices requiring operation down to 2.7 V.
