AS1362-BTTT-25

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

The AS1362-BTTT-25 is a low-dropout linear regulator delivering up to 300mA continuous output current with a preset 2.5V output voltage. It features an ultra-low noise of 9µVRMS and high power-supply rejection ratio exceeding 80dB up to 10kHz. The device operates within a 2V to 5.5V input range and maintains stability using only a 1µF ceramic output capacitor. Quiescent current is extremely low at 40µA, dropping below 500nA in shutdown mode.

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

Verify the specific ordering code AS1362-BTTT-25 against manufacturer documentation to confirm the 2.5V fixed output and 300mA load rating. Ensure compatibility with TSOT23 6-pin surface mount assembly processes. Confirm RoHS compliance status as indicated in official datasheets before finalizing procurement specifications.

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

Select this component when applications require minimal output noise and high PSRR for sensitive analog or RF circuits. The 300mA capacity supports moderate load requirements while maintaining efficiency through low dropout characteristics. Verify that the system input voltage remains within the specified 2V to 5.5V range for proper regulation.

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

This part belongs to the AS1361/AS1362 series of ultra-low-noise LDOs designed for space-limited portable electronics. The AS1362 variant specifically provides 300mA output capability compared to the 150mA AS1361. Both utilize a P-channel MOSFET pass transistor to minimize quiescent current consumption during operation.

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

Direct substitutes include other parts from the AS1361/AS1362 family with matching output voltages and current ratings. Verify pinout compatibility with the TSOT23 6-pin package and ensure equivalent noise and PSRR specifications are met for sensitive application environments.

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

What is the minimum output capacitance required for stability?

The device requires only a 1µF ceramic capacitor at the output pin for stability across any load condition.

How does the Power-OK function operate?

The Power-OK pin is an active-low, open-drain output that indicates if the output voltage is within regulation limits.

What is the quiescent current in shutdown mode?

When disabled via the SHDNN pin, current consumption drops below 500nA.
