AS1359-BTTT-33

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

The AS1359-BTTT-33 is a low-dropout linear regulator delivering a fixed 3.3V output with a maximum continuous current of 300mA. It operates from an input voltage range of 2V to 5.5V and achieves a dropout voltage as low as 140mV at full load. The device features ultra-low output noise of 9µVRMS and high power-supply rejection ratio exceeding 80dB up to 10kHz. Quiescent current is maintained at 40µA, dropping below 500nA in shutdown mode. It utilizes a TSOT23 5-pin package and requires only 1µF ceramic capacitors for stability.

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

Verify the specific ordering code AS1359-BTTT-33 against manufacturer documentation to confirm the 3.3V fixed output and 300mA current rating. Ensure compatibility with the required TSOT23 5-pin surface mount package. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature range. Check for RoHS compliance status if required by local regulations.

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

Select this component when designing space-constrained portable electronics requiring stable power delivery under varying load conditions. The low dropout characteristic allows efficient operation near battery depletion levels. The integrated thermal protection and current limiting provide robustness against short circuits and overheating without external protection components.

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

This part belongs to the AS1358/AS1359 series of ultra-low-noise LDOs manufactured by austriamicrosystems AG. The series differentiates models primarily by maximum output current capabilities, with the AS1359 variant supporting higher loads compared to the AS1358. Both share identical architectural features including the noise bypass pin and shutdown logic.
