AS1363-BSTT-30

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

The AS1363-BSTT-30 is a low-dropout linear voltage regulator manufactured by ams-OSRAM USA INC. It operates from an input voltage range of +2.0V to +5.5V and delivers a guaranteed 500mA load current with a typical dropout voltage of 150mV at full load. This specific variant provides a factory-preset output voltage of 3.0V, which is internally trimmed for high accuracy within ±1.5% over the operating temperature range. The device features a low quiescent current of 40µA typ. and a shutdown supply current of 30nA typ. It includes an active-low open-drain Power OK (POK) output, thermal overload protection, and output current limiting. The component is housed in a 6-pin SOT23 package.

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

Verify that the ordering code matches AS1363-BSTT-30 to ensure the correct 3.0V preset output. Confirm the delivery form is Tape and Reel as specified in the datasheet. Ensure the manufacturer is identified as austriamicrosystems AG or ams-OSRAM USA INC. Check for RoHS compliance status if required by your manufacturing standards.

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

Select this part when a stable 3.0V rail is required for battery-powered systems. It is suitable for applications needing low quiescent current to extend battery life. Ensure the input voltage remains above 2.0V and consider thermal dissipation limits if the voltage differential between input and output is high under heavy loads.

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

This component belongs to the AS1363 series of low-dropout linear regulators designed specifically for portable electronics. The series offers both adjustable and fixed output versions in a compact 6-pin SOT23 package. The BSTT suffix indicates the tape and reel packaging format, while the '30' designation specifies the 3.0V fixed output voltage variant.

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

Direct substitutes include other AS1363 variants with different fixed voltages (e.g., AS1363-BSTT-33 for 3.3V) if the voltage requirement changes. Adjustable versions like AS1363-BSTT-AD can be used if external resistors are added to set the desired output voltage. Verify pin compatibility and thermal characteristics before substitution.

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

How is the output voltage configured for the AS1363-BSTT-30?

The output voltage is factory-preset to 3.0V and internally trimmed. No external resistors are required for voltage setting.

What is the purpose of the POK pin?

The POK pin is an open-drain Power OK output that goes low when the output voltage falls below its nominal value, indicating a regulation fault or shutdown condition.

Can the AS1363-BSTT-30 be short-circuited indefinitely?

Yes, the device includes output current limiting and thermal overload protection, allowing it to withstand indefinite short-circuit conditions without damage.
