AS1367-BTDT-12

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

The AS1367-BTDT-12 is a fixed-output linear regulator providing 1.2V at up to 150mA. It operates with an input voltage range of 2.0V to 5.5V and features adaptive low-dropout operation for high efficiency. Key electrical parameters include a typical quiescent current of 10µA, shutdown current of 100nA, and output noise of 15µV RMS. The device includes integrated protections such as overcurrent limiting, thermal shutdown at 160°C, and under-voltage lockout.

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

Verify the specific ordering code AS1367-BTDT-12 against manufacturer documentation to confirm the 1.2V fixed output configuration. Ensure compatibility with the required 8-pin TDFN 2x2 package footprint. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature range. Check for any end-of-life or obsolescence notices from the manufacturer prior to final design approval.

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

Select this component when a stable 1.2V rail is required with minimal static power draw. The adaptive architecture suits battery-powered systems where efficiency varies with load. Verify that the maximum output current requirement does not exceed 150mA. Ensure the input voltage stays within the 2.0V to 5.5V window to maintain proper dropout performance and regulation stability.

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

This part belongs to the AS1367 series of adaptive low-dropout linear regulators manufactured by ams OSRAM. The series offers various fixed output voltages ranging from 1.2V to 5.0V in 50mV steps. All variants share the same 8-pin TDFN 2x2 package and core protection features, differing primarily in their factory-set output voltage levels defined by the suffix codes.

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

Other AS1367 variants (e.g., AS1367-BTDT-18, AS1367-BTDT-30) are pin-compatible but provide different fixed output voltages. If a different voltage is acceptable, these direct substitutes can be used without schematic changes.
