AS1362-BTTT-18

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

The AS1362-BTTT-18 is a low-dropout linear regulator delivering a fixed 1.8V output with a maximum continuous load current of 300mA. It features an ultra-low noise profile of 9µVRMS and high power-supply rejection ratio exceeding 80dB up to 10kHz. The device operates within a 2V to 5.5V input range, achieving a dropout voltage as low as 140mV at full load. Integrated protection includes overcurrent limiting and thermal shutdown. It utilizes a TSOT23-6 package and requires only 1µF ceramic capacitors for stability.

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

Verify the specific ordering code AS1362-BTTT-18 against manufacturer documentation to confirm the 1.8V preset output and 300mA current rating. Ensure compatibility with the required TSOT23-6 surface-mount package dimensions. Confirm RoHS compliance and lead-free finish specifications prior to integration into the final assembly process.

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

Select this component when designing space-constrained portable systems requiring clean power rails for RF or sensor modules. The 1.8V output suits modern logic families and memory interfaces. Evaluate the thermal resistance of the PCB layout to ensure junction temperatures remain within safe limits during peak load conditions and high ambient temperatures.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the AS1361/AS1362 series of ultra-low-noise LDOs from ams-OSRAM. While the AS1361 variant supports 150mA loads, the AS1362 provides double the current capacity at 300mA. Both share identical pinouts, noise characteristics, and package styles, allowing for flexible design scaling based on specific power requirements.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct functional equivalents include the AS1361-BTTT-18 if the system load does not exceed 150mA. Verify that any substitute maintains the same TSOT23-6 footprint and 1.8V output voltage to ensure board-level compatibility without redesigning the passive components.
