AS1376-BTDT-AD

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AS1376-BTDT-AD is a dual supply rail linear regulator delivering up to 1A load current with typical quiescent currents of 67µA and shutdown currents of 20nA. It features an ultra-low dropout voltage of 120mV at full load. The device operates with a main input voltage range of 0.7V to 3.6V and a bias supply range of 2.5V to 5.5V. This adjustable variant allows output voltage setting via external resistors, offering ±2% accuracy over the -40°C to +85°C operating temperature range.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Dual supply architecture utilizing separate VIN and VBIAS rails to maintain regulation at low input voltages
• Integrated auto-discharge function that rapidly drains load capacitance upon shutdown
• Built-in protection mechanisms including thermal overload, over-current limiting, and under-voltage lockout
• High power-supply rejection ratio across wide frequency bands for stable noise filtering

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• Post-regulation stages following host DC-DC converters in mobile devices
• Powering battery-operated portable electronics such as PDAs and digital cameras
• Low-dropout regulation for cordless phones and handheld computers
• Audio and video signal conditioning requiring clean power supplies

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific AD suffix indicates the adjustable output configuration rather than a fixed voltage variant. Confirm package compatibility with the 8-pin TDFN footprint during PCB layout. Ensure design margins account for the specified thermal resistance and junction temperature limits under maximum load conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when input voltages drop below standard LDO thresholds while maintaining high efficiency. The dual-rail design supports applications requiring fast transient response and minimal dropout. Evaluate thermal dissipation requirements carefully due to the series pass transistor characteristics under heavy loads.
