Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for AS1358-BTTT-285

AS1358-BTTT-285

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

The AS1358-BTTT-285 is a low-dropout linear regulator delivering a fixed 2.85V output with a maximum continuous current of 150mA. It operates from an input voltage range of 2V to 5.5V and achieves a dropout voltage as low as 95mV 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. Stability is ensured using only a 1µF ceramic output capacitor.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

Ultra-low noise architecture achieving 9µVRMS output noise for sensitive analog circuits
High power-supply rejection ratio exceeding 80dB across the audio frequency spectrum
Integrated P-channel MOSFET pass transistor enabling extremely low quiescent current consumption
Low dropout voltage performance allowing operation near battery depletion levels

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

Mobile phones and wireless communication devices
Bluetooth portable radios and accessories
Digital cameras and personal audio devices
Battery-powered handheld computers and PDAs

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

Verify the specific ordering code AS1358-BTTT-285 against the manufacturer's official documentation to confirm the 2.85V preset output and 150mA current rating. Ensure compatibility with the TSOT23 5-pin package dimensions and thermal requirements. Confirm RoHS compliance status if required by your manufacturing standards before finalizing procurement.

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

Select this component when designing space-constrained portable electronics requiring stable power delivery with minimal noise interference. The 150mA current limit suits moderate load applications, while the 2.85V fixed output targets specific logic or sensor supply rails. Consider the 1µF ceramic capacitor requirement for stability and verify that the input voltage remains within the specified 2V to 5.5V operational window.

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

This part belongs to the AS1358/AS1359 family of ultra-low-noise LDOs manufactured by austriamicrosystems AG (now onsemi). The AS1358 variant specifically provides 150mA output capability, distinguishing it from the higher-current AS1359 model. The BTTT suffix indicates tape and reel packaging, suitable for automated surface-mount assembly processes.

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

Consult the manufacturer's cross-reference tool for compatible alternatives. Verify pinout compatibility and electrical specifications such as dropout voltage and quiescent current when evaluating substitutes from other manufacturers.
